6.8. Interrupt Edge Select Register (integs), IO address = 0x0c

Bit

Reset

R/W

Description

7 - 5

Reserved.

Timer16 edge selection.

0 : rising edge to trigger interrupt

1 : falling edge to trigger interrupt

3 - 2

PB0 edge selection.

00 : both rising edge and falling edge to trigger interrupt

01 : rising edge to trigger interrupt

10 : falling edge to trigger interrupt

11 : reserved.

1 - 0

PA0 edge selection.

00 : both rising edge and falling edge to trigger interrupt

01 : rising edge to trigger interrupt

10 : falling edge to trigger interrupt

11 : reserved.

6.9. Port A Digital Input Enable Register (padier), IO address = 0x0d

Bit

Reset

R/W

Description

7 - 6

Enable PA7~PA6 digital input and wake up event.

1 / 0 : enable / disable.

These bits should be set to low to prevent leakage current when external crystal oscillator is

used. If these bits are set to low, PA7~PA6 can NOT be used to wake-up the system.

5 - 3

111

Enable PA5~PA3 digital input and wake up event.

1 / 0 : enable / disable.

If these bits are set to low, PA5~PA3 can NOT be used to wake-up the system.

2 - 1

Reserved.

Enable PA0 digital input, wake up event and interrupt request.

1 / 0 : enable / disable.

This bit can be set to low to disable wake up from PA0 toggling and interrupt request from

this pin.

6.10. Port B Digital Input Enable Register (pbdier), IO address = 0x0e

Bit

Reset

R/W

Description

7 - 1

0xFF

Enable PB7~PB1 digital input and wake up event.

1 / 0 : enable / disable.

When this bit is “0”, PA7~PA1 can NOT be used to wake-up the system.

Enable PA0 digital input, wake up event and interrupt request.

1 / 0 : enable / disable.

This bit can be set to low to disable wake up from PA0 toggling and interrupt request from

this pin.

6.11. Port A Data Registers (pa), IO address = 0x10

Bit

Reset

R/W

Description

7 - 0

0x00

R/W

Data registers for Port A.
