Chapter 30 I/O Ports

3.Port Register Settings

Remark: This pin supports external interrupt wake up from STOP-HIZ mode. Because of this

the internal input line is not forced to low in STOP-HIZ mode if the PFR is set to ‘1’ and
interrupt is enabled with ENIR0.EN2 set to ‘1’.

PFR24.1

0 - Port is in general purpose port mode.
1 - Port is in resource function mode:

Resource function is INT1 input

Remark: This pin supports external interrupt wake up from STOP-HIZ mode. Because of this

the internal input line is not forced to low in STOP-HIZ mode if the PFR is set to ‘1’ and
interrupt is enabled with ENIR0.EN1 set to ‘1’.

PFR24.0

0 - Port is in general purpose port mode.
1 - Port is in resource function mode:

Resource function is INT0 input

Remark: This pin supports external interrupt wake up from STOP-HIZ mode. Because of this

the internal input line is not forced to low in STOP-HIZ mode if the PFR is set to ‘1’ and
interrupt is enabled with ENIR0.EN0 set to ‘1’.

Remark: It is generally possible to use input only resource functions (like e.g. INT, ICU, CAN.RX, UART.SIN)
also in the Port I/O input mode (PFR=’0’ and DDR=’0’). In that case the internal input line is forced to low in
STOP-HIZ mode.
