10.9
PORTH is an 8-bit wide, bidirectional I/O port. PORTH
pins <3:0> are digital only and tolerate voltages up to
5.5V.
All pins on PORTH are implemented with Schmitt
Trigger input buffers. Each pin is individually
configurable as an input or output.
When the external memory interface is enabled, four of
the PORTH pins function as the high-order address
lines for the interface. The address output from the
interface takes priority over other digital I/O. The
corresponding TRISH bits are also overridden. PORTH
pins, RH4 through RH7, are multiplexed with analog
converter inputs. The operation of these pins as analog
inputs is selected by clearing or setting the
corresponding bits in the ANCON1 register. RH3 to
RH6 is multiplexed with Parallel Master Port and RH4
to RH6 are multiplexed as comparator pins.

Note:
PORTH, LATH and
TRISH Registers
PORTH is available only on 80-pin
devices.
PIC18F87J50 FAMILY
PORTH can also be configured as the alternate
Enhanced PWM output channels B and C for the
ECCP1 and ECCP3 modules. This is done by clearing
the ECCPMX Configuration bit.
