PIC18F8722 FAMILY

PORTH is an 8-bit wide, bidirectional I/O port. The
corresponding data direction register is TRISH. Setting
a TRISH bit (= 1) will make the corresponding PORTH
pin an input (i.e., put the corresponding output driver in
a high-impedance mode). Clearing a TRISH bit (= 0)
will make the corresponding PORTH pin an output
selected pin).
The Data Latch register (LATH) is also memory
mapped. Read-modify-write operations on the LATH
register, read and write the latched output value for
PORTH.
All pins on PORTH are implemented with Schmitt
Trigger input buffers. Each pin is individually
configurable as an input or output.

Preliminary
on
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.
