3.4.1 Reset Source Identification Register (RSID - 0x400F C180)
This register contains one bit for each source of Reset. Writing a 1 to any of these bits
clears the corresponding read-side bit to 0. The interactions among the four sources are
described below.

Reset Source Identification register (RSID - address 0x400F C180) bit description
Assertion of the POR signal sets this bit, and clears all of the other bits in
this register. But if another Reset signal (e.g., External Reset) remains
asserted after the POR signal is negated, then its bit is set. This bit is not
affected by any of the other sources of Reset.
Assertion of the RESET signal sets this bit. This bit is cleared only by
software or POR.
This bit is set when the Watchdog Timer times out and the WDTRESET bit
in the Watchdog Mode Register is 1. This bit is cleared only by software or
POR.
This bit is set when the V
BOD reset trip level (typically 1.85 V under nominal room temperature
conditions).
If the V
the BOD reset trip level and recovers, the BODR bit will be set to 1.
If the V
the BOD reset trip level and continues to decline to the level at which POR
is asserted (nominally 1 V), the BODR bit is cleared.
If the V
above the BOD reset trip level, the BODR will be set to 1.
This bit is cleared only by software or POR.
Note: Only in the case where a reset occurs and the POR = 0, the BODR
bit indicates if the V
or not.
Reserved, user software should not write ones to reserved bits. The value
read from a reserved bit is not defined.
