Input/Output Ports
7.18 Port H (PH0 through PH7)
The port H is a general-purpose, 8-bit input/output port. For this port, inputs and outputs can be specified in
units of bits by using the control register PHCR and the function registers PHFC1 and PHFC2. A reset allows all
bits of the output latch PH to be set to "1," all bits of PHCR to be cleared to "0," and the port H to be put in input
mode.
Input is disabled right after reset. To enable input, set the corresponding bit of PHIE to “1”.
Besides the port function, the port H inputs external interrupts and a 16-bit timer.
