occurred during the STOP period. If the device is reset to exit STOP
mode, then no input capture flag or data remains, even if a valid input
capture edge occurred.

contents and the status of the flag bits are shown in the following
diagrams. It should be noted that the signals labelled ‘internal’
(processor clock, timer clocks and reset) are not available to the user.
