4.5.1.1 Reset Configuration Word Low Register (RCWLR)
The reset configuration word low register (RCWLR) is shown in
Section 4.3.2.1, "Reset Configuration Word Low Register (RCWLR)."
4.5.1.2 Reset Configuration Word High Register (RCWHR)
The reset configuration word high register (RCWHR) is shown in
Section 4.3.2.2, "Reset Configuration Word High Register (RCWHR)."
4.5.1.3 Reset Status Register (RSR)
RSR, shown in Figure
For example, because software watchdog expiration results in a hard reset, SWRS and HRS are all set after
a software watchdog reset. This register returns to its reset value only when power-on reset occurs.
