9.4
Port 7 is a general I/O port also functioning as a timer V I/O pin. Each pin of the port 7 is shown
in figure 9.4. The register setting of TCSRV in timer V has priority for functions of the
P76/TMOV pin. The pins, P75/TMCIV and P74/TMRIV, are also functioning as timer V input
ports that are connected to the timer V regardless of the register setting of port 7.
Port 7 has the following registers.

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.
