Time-out counter comparison value
If "TOUTen" is set, the "TOUTcnt[0:6] will be reset first and then start
counting whenever a new PPI transfer cycle is initiated. On detecting
TOUTcnt[0:6] is equal to TOUTcmp[1:7], a "Time Out" flag will be set
which in turn trigger a interrupt request (Irpt_TOUT) if IER[2]
(ToutIen) is also set at that time. The tick of Time-Out Counter is
about 9.175ms (OSC/(2**21) where OSC = 14.318MHz). The
maximum duration that Time-Out Counter can cover is about 1.17 sec
(2**7 ticks).
