8.5 Timer During Wait Mode
The CPU clock halts during the wait mode, but the timer remains active.
If interrupts are enabled, a timer interrupt will cause the processor to exit
the wait mode.
8.6 Timer During Stop Mode
In the 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 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.
