PIC18F85J11 FAMILY
11.6
PORTE is an 8-bit wide, bidirectional port. The corre-
sponding Data Direction and Output Latch registers are
TRISE and LATE. All pins on PORTE are digital only
and tolerate voltages up to 5.5V.
All pins on PORTE are implemented with Schmitt Trig-
ger input buffers. Each pin is individually configurable
as an input or output. The RE7 pin is also configurable
for open-drain output when CCP2 is active on this pin.
Open-drain configuration is selected by setting the
CCP2OD control bit (TRISG<6>)
Each of the PORTE pins has a weak internal pull-up. A
single control bit can turn off all the pull-ups. This is
performed by clearing bit, REPU (PORTG<6>). The
weak pull-up is automatically turned off when the port
pin is configured as an output. The pull-ups are
disabled on any device Reset.
On 80-pin devices, PORTE is multiplexed with the
system bus as part of the external memory interface.
I/O port and other functions are only available when the
interface is disabled by setting the EBDIS bit
(MEMCON<7>). When the interface is enabled,
PORTE is the high-order byte of the multiplexed
address/data bus (AD<15:8>). The TRISE bits are also
overridden.

Note:
PORTE, TRISE and
LATE Registers
These pins are configured as digital inputs
on any device Reset.
When the Parallel Slave Port is active on PORTD, three
of the PORTE pins (RE0, RE1 and RE2) are configured
as digital control inputs for the port. The control
functions are summarized in Table 11-11. The reconfig-
uration occurs automatically when the PSPMODE
control bit (PSPCON<4>) is set. Users must still make
certain the corresponding TRISE bits are set to
configure these pins as digital inputs.
RE7 can also be configured as the alternate peripheral
pin for the CCP2 module. This is done by clearing the
CCP2MX Configuration bit.
