Preliminary
LATA<0> data output.
PORTA<0> data input.
A/D input channel 0. Enabled on POR, this analog input overrides the
digital input (read as clear – low level).
Comparator voltage reference analog output. Enabling this analog
output overrides the digital I/O (read as clear – low level).
LATA<1> data output.
PORTA<1> data input.
A/D input channel 1. Enabled on POR, this analog input overrides the
digital input (read as clear – low level).
LATA<2> data output.
PORTA<2> data input.
A/D input channel 2. Enabled on POR, this analog input overrides the
digital input (read as clear – low level).
A/D and comparator negative voltage analog input.
LATA<3> data output.
PORTA<3> data input.
A/D input channel 3. Enabled on POR, this analog input overrides the
digital input (read as clear – low level).
