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’ Table 12. This command terminates the MCU activity. The termination

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 Table 20.
