( ) ...M37280EKSP Connected to VSS. To enter the reset state, the reset input pin must be kept at a LOW for 2 µs or more (under normal VCC conditions). If more time is needed for the quartz-crystal oscillator to stabilize, this LOW condition should be maintained 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 pins XIN and XOUT. If an external clock is used, the clock source should be connected to the XIN pin and the XOUT pin should be left open. Port P0 is an 8-bit I/O port with direction register 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 of P03 is CMOS output, that of P00–P02 and P04–P07 are N-channel open-drain output. See notes at end of Table for full details of port P0 functions. Pins P00–P03 and P04–P07 are also used as 8-bit PWM output pins PWM4–PWM7 and PWM0–PWM3 respectively. The output structure of PWM0–PWM6 is N-channel open-drain output. And the output structure of PWM7 is CMOS output. Port P1 is an 8-bit I/O port and has basically the same functions as port P0. The output structure of P10 and P15–P17 is CMOS output, that of P11–P14 is N-channel open-drain output. Pin P10, P15–P17 are also used as OSD output pins OUT2, G0, B0, R0, respectively. The output structure is CMOS output. Pin P11–P14 are used as SCL1, SCL2, SDA1 and SDA2 respectively, when multi-master I2C-BUS interface is used. The output structure is N-channel open-drain output. Pin P16 is also used as extemal interrupt input pin INT3. Pin P17 is also used as serial I/O data input pin SIN. Port P2 is an 8-bit I/O port and has basically the same functions as port P0. The output structure is CMOS output. Pins P24–P26, P27 are also used as analog input pins AD3–AD1, AD5 respectively. 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. Pins P30, P31 are also used as analog input pins AD7, AD8 respectively. Ports P32 is a 1-bit output port. The output structure is N-channel open-drain output. Ports P40–P46 are a 7-bit input port. Pin P40 is also used as analog input pin AD4. Pins P41, P44 are also used as external interrupt input pins INT2, INT1. Pins P42 and P43 are also used as external clock input pins TIM2, TIM3 respectively. Pin P45 is used as serial I/O data output pin SOUT. The output structure is N-channel open- drain output. Pin P46 is used as serial I/O synchronous clock input/output pin SCLK. The output structure is N-channel open-drain output. Port P47 is a 1-bit output port. The output structure is N-channel open-drain output.
