Clock failure -->

Clock Monitor failure -->
Scenario 1: OSCCLK recovers prior to exiting Pseudo-Stop Mode.
Scenario 2: OSCCLK does not recover prior to exiting Pseudo-Stop Mode.
Table 9-12. Outcome of Clock Loss in Pseudo-Stop Mode
No action, clock loss not detected.
CRG performs Clock Monitor Reset immediately
– MCU remains in Pseudo-Stop Mode,
– VREG enabled,
– PLL enabled,
– SCM activated,
– Start Clock Quality Check,
– Set SCMIF interrupt flag.
Some time later OSCCLK recovers.
– CM no longer indicates a failure,
– 4096 OSCCLK cycles later Clock Quality Check indicates clock o.k.,
– SCM deactivated,
– PLL disabled,
– VREG disabled.
– MCU remains in Pseudo-Stop Mode.
Some time later either a wakeup interrupt occurs (no SCM interrupt)
– Exit Pseudo-Stop Mode using OSCCLK as system clock (SYSCLK),
– Continue normal operation.
– Exit Pseudo-Stop Mode using OSCCLK as system clock,
– Start reset sequence.
– MCU remains in Pseudo-Stop Mode,
– VREG enabled,
– PLL enabled,
– SCM activated,
– Start Clock Quality Check,
– Set SCMIF interrupt flag,
– Keep performing Clock Quality Checks (could continue infinitely)
Some time later either a wakeup interrupt occurs (no SCM interrupt)
– Exit Pseudo-Stop Mode in SCM using PLL clock (f
– Continue to perform additional Clock Quality Checks until OSCCLK
or an External RESET is applied.
