Description

Enable PA7 digital input and wake-up event.

1 / 0 : enable / disable.

This bit should be set to low to prevent leakage current when external crystal oscillator

is used. If this bit is set to low, PA7 can NOT be used to wake-up the system.

Note: For ICE emulation, the function is disabled when this bit is “1” and “0” is enabled.

Enable PA6 digital input and wake-up event.

1 / 0 : enable / disable.

This bit should be set to low to prevent leakage current when external crystal oscillator

is used. If this bit is set to low, PA6 can NOT be used to wake-up the system.

Note: For ICE emulation, the function is disabled when this bit is “1” and “0” is enabled.

Enable PA5 wake-up event.

1 / 0 : enable / disable.

This bit can be set to low to disable wake-up from PA5 toggling.

Note: For ICE emulation, wakeup is disabled when this bit is “1” and “0” is enabled.

Enable PA4 digital input and wake-up event.

1 / 0 : enable / disable.

This bit should be set to low when PA4 is assigned as AD input to prevent leakage

current. If this bit is set to low, PA4 can NOT be used to wake-up the system.

Note: For ICE emulation, the function is disabled when this bit is “1” and “0” is enabled.

Enable PA3 digital input and wake-up event.

1 / 0 : enable / disable.

This bit should be set to low when PA3 is assigned as AD input to prevent leakage

current. If this bit is set to low, PA3 can NOT be used to wake-up the system.

Note: For ICE emulation, the function is disabled when this bit is “1” and “0” is enabled.

Enable PA2 wake-up event.

1 / 0 : enable / disable.

This bit can be set to low to disable wake-up from PA2 toggling.

Note: For ICE emulation, wakeup is disabled when this bit is “1” and “0” is enabled.

Enable PA1 wake-up event.

1 / 0 : enable / disable.

This bit can be set to low to disable wake-up from PA1 toggling.

Note: For ICE emulation, wakeup is disabled when this bit is “1” and “0” is enabled.

Enable PA0 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.

Note: For ICE emulation, the function is disabled when this bit is “1” and “0” is enabled.

Note: Due to the controlling polarity of this register is different between ICE and real chip. In order to unify the

program for both ICE emulation and real chip to be the same one, please use the following command to write this

“$ PADIER

0xhh” ;

For example:

$ PADIER

0xF0;

It is used to enable the digital input and wakeup function of bit [7:4] of port A for both ICE and real chip, IDE will

handle the difference between ICE and real chip automatically.
