Chapter 30 I/O Ports
3.Port Register Settings
Resource function is RX0 input, and INT8 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 ENIR1.EN8 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.
