Architectural overview
ARM7TDMI-S general purpose 32-bit microprocessor, which offers high performance very power consumption. architecture based Reduced Instruction Computer (RISC) principles, instruction related decode mechanism much simpler than those microprogrammed Complex Instruction Computers. This simplicity results high instruction throughput impressive real-time interrupt response from small cost-effective processor core. Pipeline techniques employed that parts processing memory systems operate continuously. Typically, while instruction being executed, successor being decoded, third instruction being fetched from memory. ARM7TDMI-S processor also employs unique architectural strategy known Thumb, which makes ideally suited high-volume applications with memory restrictions, applications where code density issue. idea behind Thumb that super-reduced instruction set. Essentially, ARM7TDMI-S processor instruction sets:
standard 32-bit set. 16-bit Thumb set.
Thumb set's 16-bit instruction length allows approach twice density standard code while retaining most ARM's performance advantage over traditional 16-bit processor using 16-bit registers. This possible because Thumb code operates same 32-bit register code. Thumb code able provide code size ARM, performance equivalent processor connected 16-bit memory system.

Timer designed count cycles peripheral clock (PCLK) optionally generate interrupts perform other actions when specified timer values occur, based seven match registers. function also based match register events. ability separately control rising falling edge locations allows used more applications. instance, multi-phase motor control typically requires three non-overlapping outputs with individual control three pulse widths positions. match registers used provide single edge controlled output. match register (MR0) controls cycle rate, resetting count upon match. other match register controls edge position. Additional single edge controlled outputs require only match register each, since repetition rate same outputs. Multiple single edge controlled outputs will have rising edge beginning each cycle, when match occurs. Three match registers used provide output with both edges controlled. Again, match register controls cycle rate. other match registers control edge positions. Additional double edge controlled outputs require only match registers each, since repetition rate same outputs.

With double edge controlled outputs, specific match registers control rising falling edge output. This allows both positive going pulses (when rising edge occurs prior falling edge), negative going pulses (when falling edge occurs prior rising edge).
6.17.1 Features
Seven match registers allow single edge controlled three double edge
controlled outputs, both types.
match registers also allow:
Continuous operation with optional interrupt generation match. Stop timer match with optional interrupt generation. Reset timer match with optional interrupt generation.
Supports single edge controlled and/or double edge controlled outputs. Single
edge controlled outputs HIGH beginning each cycle unless output constant LOW. Double edge controlled outputs have either edge occur position within cycle. This allows both positive going negative going pulses.
Pulse period width number timer counts. This allows complete
flexibility trade-off between resolution repetition rate. outputs will occur same repetition rate.
Double edge controlled outputs programmed either positive going
negative going pulses.
Match register updates synchronized with pulse outputs prevent generation
erroneous pulses. Software must `release' match values before they become effective.

Assertion chip Reset source starts Wake-up Timer (see Wake-up Timer description below), causing internal chip reset remain asserted until external Reset de-asserted, oscillator running, fixed number clocks have passed, on-chip flash controller completed initialization. When internal Reset removed, processor begins executing address which Reset vector. that point, processor peripheral registers have been initialized predetermined values. Wake-up Timer ensures that oscillator other analog functions required chip operation fully functional before processor allowed execute instructions. This important power types Reset, whenever aforementioned functions turned reason. Since oscillator other functions turned during Power-down mode, wake-up processor from Power-down mode makes Wake-up Timer. Wake-up Timer monitors crystal oscillator means checking whether safe begin code execution. When power applied chip, some event caused chip exit Power-down mode, some time required oscillator produce signal sufficient amplitude drive clock logic. amount time depends many factors, including rate ramp case power on), type crystal electrical characteristics quartz crystal used), well other external circuitry (e.g., capacitors), characteristics oscillator itself under existing ambient conditions.

Memory Mapping Control alters mapping interrupt vectors that appear beginning address 0x0000 0000. Vectors mapped bottom on-chip flash memory, on-chip SRAM. This allows code running different memory spaces have control interrupts.
6.18.7 Power control
LPC2194 support reduced power modes: Idle mode Power-down mode. Idle mode, execution instructions suspended until either Reset interrupt occurs. Peripheral functions continue operation during Idle mode generate interrupts cause processor resume execution. Idle mode eliminates power used processor itself, memory systems related controllers, internal buses. Power-down mode, oscillator shut down chip receives internal clocks. processor state registers, peripheral registers, internal SRAM values preserved throughout Power-down mode logic levels chip output pins remain static. Power-down mode terminated normal operation resumed either Reset certain specific interrupts that able function without clocks. Since dynamic operation chip suspended, Power-down mode reduces chip power consumption nearly zero. Power Control Peripherals feature allows individual peripherals turned they needed application, resulting additional power savings.
