DESCRIPTION

Power

Ground

Input pin for 32.768 kHz oscillator

Output pin for 32.768 kHz oscillator

Phase loop lock capacitor, connect a capacitor 0.047u to 0.1u to the ground.

ERIC mode clock signal input. This pin is shared with PLLC.

Counter1 external CLK input. This pin is shared with P94.

Note the frequency of the input CLK must less than 1M Hz.

ADC external reference voltage input

ADC input channel 1. Shared with PORT90

ADC input channel 2. Shared with PORT91

ADC input channel 3. Shared with PORT62

ADC input channel 4. Shared with PORT63

ADC input channel 5. Shared with PORT64

ADC input channel 6. Shared with PORT65

ADC input channel 7. Shared with PORT92

ADC input channel 8. Shared with PORT93

Pulse width modulation output

This pin shared with PORTC1

Pulse width modulation output

This pin shared with PORTC2

PORT60,1 can be INPUT or OUTPUT port each bit.. These two pins can be

used on ERIC and IRC modes.

PORT6 can be INPUT or OUTPUT port each bit.

PORT70 can be INPUT or OUTPUT port each bit.

PORT71 is INPUT only.

PORT7 can be INPUT or OUTPUT port each bit.

PORT9 can be INPUT or OUTPUT port each bit.

PORTC can be INPUT or OUTPUT port each bit.

Interrupt sources. Once PORT70 has a falling edge or rising edge signal

(controlled by CONT register), it will generate a interruption.

Interrupt sources which has the same interrupt flag. Any pin from PORT71

has a falling edge signal, it will generate a interruption.

Interrupt sources which has the same interrupt flag. Any pin from PORT73

has a falling edge signal, it will generate a interruption.

Low reset
