g) The TRIS registers control only the digital I/O
output buffer. Any other dedicated or remap-
pable active “output” will automatically over-
ride the TRIS setting. The TRIS register does
not control the digital logic “input” buffer.
Remappable digital “inputs” do not automati-
cally override TRIS settings which means that
the TRIS bit must be set to input for pins with
only remappable input function(s) assigned.
h) All analog pins are enabled by default after
any reset and the corresponding digital input
buffer on the pin is disabled. Only the Analog
pin select registers control the digital input
buffer, not the TRIS register. The user must
disable the analog function on a pin using the
analog pin select registers in order to use any
“digital input(s)” on a corresponding pin, no
exceptions.
