If the pattern detection fails the internal wake-up (on all active channels) is terminated with no signal sent to MCU and the false wakeup register
will be incremented (R13<7:0>).
The wake-up state is terminated with the direct command ‘clear_wake’
can also be automatic in case there is no response from MCU. The time out for automatic termination is set in a register R7<7:5>, as shown in
the
