the beginning (Config A, Channel 1) until the on time has elapsed. The timing calculation
can be seen in the next figure. Note that Permanent Wake Up Search makes sense only
in the Const On/Off Mode.

Note: Calculation of On/Off Time and Master Period is equal to Fast Fall Back to Sleep
Wake Up Mode.
2.4.6.6
This is used to deactivate some polling periods. Normally, the polling starts again after
the T
deactivated independently from the polling mode. The active and idle sequences are set
with the SPMAP and the SPMIP registers. The values of these registers determine the
factors M and N.
