Setting a PCR7 bit to 1 makes the corresponding pin an
output port, while clearing the bit to 0 makes the pin an
input port. Note that the TCSRV setting of the timer V has
priority for deciding input/output direction of the
P76/TMOV pin.

PDR7 stores output data for port 7 pins.
If PDR7 is read while PCR7 bits are set to 1, the value
stored in PDR7 is read. If PDR7 is read while PCR7 bits
are cleared to 0, the pin states are read regardless of the
value stored in PDR7.
