ALT0 is the primary (default) function for each port after reset.

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

→ ALT0;

PCR.PA = 01

→ ALT1; PCR.PA = 10 → ALT2; PCR.PA = 11 → ALT3. 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 “—”.

Module included on the MCU.

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.

Programmable via the SRC (Slew Rate Control) bits in the respective Pad Configuration Register.

ADC0.AN emulates ADC1.AN. This feature is used to provide software compatibility between SPC560P34/SPC560P40

and SPC560P50. Refer to ADC chapter of reference manual for more details.
