External signal description
The SWT module does not have any external interface signals.
4.2.5
Memory map and register description
The SWT programming model has seven 32-bit registers. The programming model can only be accessed
using 32-bit (word) accesses. References using a different size are invalid. Other types of invalid accesses
include: writes to read only registers, incorrect values written to the service register when enabled,
accesses to reserved addresses and accesses by masters without permission. If the RIA bit in the SWT_CR
is set, then the SWT generates a system reset on an invalid access. Otherwise, a bus error is generated. If
either the HLK or SLK bits in the SWT_CR are set then the SWT_CR, SWT_TO, and SWT_WN registers
are read-only.

Notes:
1) The SWT is started on Phase1 exit and counts unconditionally during Phase2 to monitor the flash memory boot sequence.
2) Value copied from configuration bit NVUSR0[WATCHDOG_EN] in the shadow flash memory (software can modify it later)
