The prefix on the SWDT I/O signal names are mapped to the watchdog timer instances:

LPD_SWDT for the RPU, located in the LPD subsystem (refer to SWDT0)
FPD_SWDT for the APU, located in the FPD subsystem (refer to SWDT1)

The I/O interface signals for the SWDT[0,1] are available on the PMC and LPD MIO pins as shown in the following table and in the tables in the MIO-at-a-Glance Tables section. The signals are described in the Signals to the Timer section.
