writes (0x0055 or 0x00AA) to the ARMCOP register must occur in the last 25% of the selected time-out
period. A premature write the CRG will immediately generate a reset.
As soon as the reset sequence is completed the reset generator checks the reset condition. If no clock
monitor failure is indicated and the latched state of the COP timeout is true, processing begins by fetching
the COP vector.
4.5.3
The on-chip voltage regulator detects when V
power-on reset or low voltage reset or both. As soon as a power-on reset or low voltage reset is triggered
the CRG performs a quality check on the incoming clock signal. As soon as clock quality check indicates
a valid oscillator clock signal the reset sequence starts using the oscillator clock. If after 50 check windows
the clock quality check indicated a non-valid oscillator clock the reset sequence starts using self-clock
mode.
