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  AF3. 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.

All WKPU pins also support external interrupt capability. See “wakeup unit” chapter of the device reference manual 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 “BAM” chapter of the

device reference manual for details.

Out of reset all the functional pins except PC[0:1] and PH[9:10] are available to the user as GPIO.

PC[0:1] are available as JTAG pins (TDI and TDO respectively).

PH[9:10] are available as JTAG pins (TCK and TMS respectively).

If the user configures these JTAG pins in GPIO mode the device is no longer compliant with IEEE 1149.1 2001.
