Functional Description
A8032 high speed 8-bit microcontroller. architecture consists core controller, four general purposes ports, bytes internal register serial port. This microcontroller supports opcodes executes instructions 6-clock cycle. reference both program address space data storage space.
Timer/Counter
Timer each consist 8-bit data registers. These called Timer Timer Timer TMOD TCON registers support control function Timer Timer T2CON register provides control function Timer When operating reload/capture mode, RCAP2H RCAP2L will used.

Interrupt
A8032 provides interrupt modes. These consist external interrupts, internal interrupts serial port interrupt. enable/disable interrupt controlled register SFR. priority interrupts controlled register SFR.
Figure External Clock Drive configuration
RESET external reset signal must held high least machine cycles during oscillator running. After reset, ports held high, register 07H, other registers except SBUF 00H, SBUF reset.
Serial Port Transfer
A8032 provides full duplex serial transfer function. This function controlled SCON register SFR. data storaged SBUF register during transmitting receiving.
Oscillator Characteristics
oscillator connections shown Figure Figure When quartz crystal used, 30pF shown Figure When external clock used, internal clock will gotten through divide-by-two flip-flop. When starting input loading XTAL1 100pF. This interaction between amplifier feedback capacitance interaction. After external signal meets specification capacitance will exceed 20pF.
