This is connected to VSS. To enter the reset state, the reset input pin must be kept at a “L” for 2 µs or more (under nor- mal VCC conditions). If more time is needed for the crystal oscillator to stabilize, this “L” condition should be main- tained for the required time. This chip has an internal clock generating circuit. To control generating frequency, an exter- nal ceramic resonator or a quartz-crystal oscillator is connected between the XIN and XOUT pins. If an external clock is used, the clock source should be connected the XIN pin and the XOUT pin should be left open. This is the timing output pin. Port P0 is an 8-bit I/O port with directional registers allowing each I/O bit to be individually programmed as input or output. At reset, this port is set to input mode. The output structure is CMOS output. The output structure is N-channel open-drain output. When PWM4, PWM5, PWM6 and PWM7 are used, P00, P01, P02 and P03 are in common with PWM output pins of PWM4, PWM5, PWM6 and PWM7. Ports P10, P11, P12, P13 and P14 are 5-bit I/O ports and have basically the same functions as port P0. The output structure is CMOS output. Ports P15, P16 and P17 are 3-bit input ports and they are in common with input pins of A-D comparator (A-D1, A-D2 and A-D3). Port P2 is an 8-bit I/O port and has basically the same functions as port P0. The output structure is CMOS output. Ports P30 and P31 are 2-bit I/O ports and have basically the same functions as port P0. The output structure is CMOS output. Ports P32, P33, P34 and P35 are 4-bit input ports and ports P32 and P33 are in common with external clock input pins of timers 2 and 3. Ports P34 and P35 are in common with external interrupt input pins INT1 and INT2. Port P35 is in common with an input pin of A-D comparator (A-D4). Ports P40 and P41 are 2-bit I/O ports and have basically the same functions as port P0. When serial I/O is used, ports P40 and P41 are in common with SOUT pin and SCLK pin, re- spectively. Port P42 is an 1-bit Input port, and it is common with an input pin of A-D comparator (A-D5) and serial input pin (SIN). Port P6 is an 4-bit output port. The output structure is N-channel open-drain. This port is in common with 6-bit PWM output pins PWM0-PWM3. This is the I/O pins of the clock generating circuit for the CRT display function. This is the horizontal synchronizing signal input for CRT display. This is the vertical synchronizing signal input for CRT display. This is a 4-bit output pin for CRT display. The output structure is CMOS output. This is in common with port P52 – P55. This is an output pin for 14-bit PWM. |
