8.5 Timer During Wait Mode
The central processor unit (CPU) clock halts during wait mode, but the
timer remains active. If interrupts are enabled, a timer interrupt will cause
the processor to exit wait mode.
8.6 Timer During Stop Mode
In stop mode, the timer stops counting and holds the last count value if
STOP is exited by an interrupt. If STOP is exited by reset, the counters
are forced to $FFFC. During STOP, if at least one valid input capture
edge occurs at the TCAP pins, the input capture detect circuit is armed.
This does not set any timer flags or wake up the microcontroller unit
(MCU). But if an interrupt is used to exit stop mode, there is an active
input capture flag and data from the first valid edge that occurred during
the stop mode. If reset is used to exit stop mode, then no input capture
flag or data remains, even if a valid input capture edge occurred.
