Description
Gives
HAPTSHORTSTAT rising edge)
Gives the ProxClose interrupt source status. (ie PROXSTAT
rising edge)
Gives
ProxConvDone (ie CONVSTAT falling edge after proximity
conversion) interrupt status depending on PROXIRQSEL .
Gives
PROXCOMPSTAT falling edge)
Gives the PenTouch/TouchConvDone interrupt source status. (ie
in PENDET mode -> PENSTAT rising edge, else -> CONVSTAT
falling edge after touch conversion)
Gives the PenRelease interrupt source status. (ie PENSTAT
falling edge)
Gives
TEMPWARNINGSTAT
TEMPWRNIRQEDG)
Gives
TEMPALARMSTAT
TEMPALRMIRQEDG)
Description
Gives the haptics short-circuit instantaneous status :
0 : No short circuit is currently present
1 : A short circuit is currently present
Gives the reset latched status :
0 : No reset occurred
1 : A reset occurred
This bit is cleared when RegStat is read.
