Some port pins are multiplexed with analog functions
such as the Analog-to-Digital Converter and compara-
tors. When these I/O pins are to be used as analog
inputs it is necessary to disable the digital input buffer
to avoid excessive current caused by improper biasing
of the digital input. Individual control of the digital input
buffers on pins which share analog functions is pro-
vided by the ANSEL and ANSELH registers. Setting an

U = Unimplemented bit, read as ‘0’
‘0’ = Bit is cleared
R/W-1
ANSx bit high will disable the associated digital input
buffer and cause all reads of that pin to return ‘0’ while
allowing analog functions of that pin to operate
correctly.
The state of the ANSx bits has no affect on digital
output functions. A pin with the associated TRISx bit
clear and ANSx bit set will still operate as a digital
output but the Input mode will be analog.
