Note 1: The Analog Debug Output is selected when the ATSTCON<BNCHEN> bit is set.
2: Selected when device is functioning as multiple output master or slave by proper configuration of the MLTPH<2:0> bits
in the BUFFCON register.
3: Selected when device is functioning as multi-phase master or slave by proper configuration of the MLTPH<2:0> bits in
the BUFFCON register.
4: The IOC is disabled when MCLR
is enabled.
5: Weak pull-up always enabled when MCLR
is enabled, otherwise the pull-up is under user control.
