PORTH is an 8-bit wide, bidirectional I/O port. The
corresponding Data Direction and Output Latch registers
are TRISH and LATH.
All pins on PORTH are implemented with Schmitt
Trigger input buffers. Each pin is individually
configurable as an input or output.
All
ADC/CCP/Comparator
controlled by the LCDSE5 register. I/O port functions are
only available when the segments are disabled.
