9.4.7.2 Device Reset Request
If the Power Monitor Module detects that the voltage source being monitored is above the
specified overvoltage level or below the undervoltage level, it asserts the
corresponding signal to inform the system of the violation. With up to six scan sources,
the Power Monitor module relies on its built-in oscillator to rotate through all the
selected voltage sources to perform its tasks. Following a violation event, a SYSRST can
occur. A SYSRST signal is asserted under the following conditions:
- A UV or OV event occurs during normal operation (Fault injection disabled).
- A UV or OV event occurs due to
Fault injection with FLTRSTEN=
1The VMxSTAT[FLTRST] indicates the source of the Fault condition after a Reset and should be read after the PWRMR bit, RCON[16], indicates a power monitor Reset as the source to see if the Reset was due to Fault injection or an actual voltage failure.
