Alternate functions are chosen by setting the values of the PCR.PA bitfields inside the SIUL module. PCR.PA = 00

 AF0; PCR.PA = 01  AF1; PCR.PA = 10  AF2;

PCR.PA = 11

 AF2. This is intended to select the output functions; to use one of the input functions, the PCR.IBE bit must be written to ‘1’, regardless of the values

selected in the PCR.PA bitfields. For this reason, the value corresponding to an input only function is reported as “—”.

Multiple inputs are routed to all respective modules internally. The input of some modules must be configured by setting the values of the PSMIO.PADSELx bitfields inside

the SIUL module.

The RESET configuration applies during and after reset.

LBGA208 available only as development package for Nexus2+

All WKPU pins also support external interrupt capability. See the WKPU chapter for further details.

NMI has higher priority than alternate function. When NMI is selected, the PCR.AF field is ignored.

“Not applicable” because these functions are available only while the device is booting. Refer to the BAM information for details.

Value of PCR.IBE bit must be 0.

This wakeup input cannot be used to exit STANDBY mode.
