Current Sense Input
The Analog Debug Output is selected when the ATSTCON<BNCHEN> bit is set.
Selected when the device is functioning as multiple output master or slave by proper configuration of the MLTPH<2:0>
bits in the BUFFCON register.
Selected when the device is functioning as multi-phase master or slave by proper configuration of the MLTPH<2:0> bits
in the BUFFCON register.
The IOC is disabled when MCLR is enabled.
Weak pull-up always enabled when MCLR is enabled, otherwise the pull-up is under user control.
