Interrupts vectored interrupts with priorities shown Table Reset also included table because operation similar interrupt. When interrupt accepted, contents program counter processor status register automatically stored into stack. interrupt disable flag corresponding interrupt request "0." jump destination address stored vector address enters program counter. Other interrupts disabled when interrupt disable flag "1." interrupts except instruction interrupt have interrupt request interrupt enable bit. interrupt request bits interrupt request registers interrupt enable bits interrupt control registers Figure shows structure interrupt-related registers. Interrupts other than instruction interrupt reset accepted when interrupt enable "1," interrupt request "1," interrupt disable flag "0." interrupt request program, "1." interrupt enable program. Reset treated non-maskable interrupt with highest priority. Figure shows interrupt control.
Interrupt Causes
VSYNC interrupts VSYNC interrupt interrupt request synchronized with vertical sync signal. interrupt occurs after character block display completed. INT1, INT2, INT3 interrupts With external interrupt input, system detects that level changes from from "L," generates interrupt request. input active edge selected bits interrupt input polarity register (address 00F916 when this "0," change from detected; when "1," change from detected.

Internal clock-the serial counter during write cycle into serial register (address 00DD16), transfer clock goes forcibly. each falling edge transfer clock after write cycle, serial data output from SOUT pin. Transfer direction selected serial mode register. each rising edge transfer clock, data input from data serial register shifted bit. After transfer clock counted times, serial counter becomes transfer clock stops "H." this time interrupt request "1." External clock-when external clock selected clock source, interrupt request after transfer clock counted times. However, transfer operation does stop, control clock externally. external clock 1MHz less with duty cycle 50%. serial timing shown Figure When using external clock transfer, external clock must held initializing serial counter. When switching between internal clock external clock, switch during transfer. Also, sure initialize serial counter after switching.

OUTPUT FUNCTION
M37220M3-XXXSP equipped with 14-bit (DA) 8-bit PWMs (PWM0-PWM5). 14-bit resolution with minimum resolution width 0.25µs (for f(XIN) MHz) repeat period 4096µs. PWM0-PWM5 have same circuit structure 8-bit resolution with minimum resolution width (for f(XIN) MHz) repeat period 1024µs. Figure shows block diagram. timing generating circuit applies individual control signals PWM0-PWM5 using f(XIN) divided reference signal.
Operating 14-bit
with 8-bit PWM, output control register (address 00D516) reset, already automatically), that count source supplied. Next, select output polarity output control register (address 00D6 16). Then, 14-bit outputs from output setting output control register reset, this already automatically) select output. output example 14-bit shown Figure 14-bit divides data latch into low-order bits high-order bits. fundamental waveform determined with high-order 8-bit data level area with length ("H" level area fundamental waveform) output every short area 64µs minimum resolution width 0.25µs). level area increase interval (tm) determined with low-order 6-bit data level smaller intervals "tm" shown Table longer than that other smaller intervals repeat period 64t. Thus, rectangular waveform with different width output from pin. Accordingly, output changes unit pulse width changing contents DA-H DA-L registers. length entirely output cannot output, 256/ 256.
Data Setting
When outputting first high-order bits DA-H register (address 00CE16 then low-order bits DA-L register (address 00CF16). When outputting PWM0-PWM5, 8-bit output data PWMi register means addresses 00D016 00D416, 00F616
Transmitting Data from Register circuit
Data transfer from 8-bit register 8-bit circuit executed writing data register. signal output from 8-bit output corresponds contents this register. Also, data transfer from register (addresses 00CE16 00CF16) 14-bit circuit executed writing data DA-L register (address 00CF16 Reading from DA-H register (address 00CE16) means reading this transferred data. Accordingly, possible confirm data being output from output reading register.
Output after Reset
reset, output port P00-P05 high-impedance state, contents register circuit undefined. Note that after reset, output undefined until setting register.
Operating 8-bit
following explanation about operation. first, output control register (address 00D516) reset, already automatically), that count source supplied. PWM0-PWM5 also used pins P00-P0 respectively. PWM0-PWM5, corresponding bits port direction register (output mode). select each output polarity output control register 2(address 00D616 Then, bits output control register (PWM output). waveform output from output pins setting these registers. Figure shows 8-bit timing. cycle composed (28) segments. kinds pulses relative weight each (bits output inside circuit during cycle. Refer Figure (a). 8-bit outputs waveform which logical (OR) pulses corresponding contents bits 8-bit register. Several examples shown Figure (b). kinds output ("H" level area: 0/256 255/256) selected changing contents register. length entirely output cannot output, i.e. 256/256.
