8.5
PORTE is an 8-bit wide, bi-directional port. The corre-
sponding Data Direction register is TRISE. Setting a
TRISE bit (=1) will make the corresponding PORTE pin
an input (i.e., put the corresponding output driver in a
hi-impedance mode). Clearing a TRISE bit (=0) will
make the corresponding PORTE pin an output (i.e., put
the contents of the output latch on the selected pin).
Read-modify-write operations on the LATE register
reads and writes the latched output value for PORTE.
PORTE is an 8-bit port with Schmitt Trigger input buff-
ers. Each pin is individually configurable as an input or
output. PORTE is multiplexed with several peripheral
functions (Table 8-9).
