I Input port pins PD0 to PD3
· These four pins can be programmed for
comparator inputs in user application
programs. PD0 input will be compared
with VREF0. Other inputs will be
compared with VREF1. Please note that
there are four comparators available in this
system and these four comparators are
grouped into two (one group: CMP0 and
CMP1. the other group: CMP2 and CMP3),
and that the comparators must be selected
in group units.
I Input port pins PE0 to PE1
· These two tristate input port pins can be
controlled in your application programs.
