register. Resetting sets port 7 to input port and all bits of output latch to 1.
(1) Port 70 (SCK, OPTRX0)
Port 7 is an 8-bit general-purpose I/O port. I/O can be set on bit basis using the control
In addition to functioning as a general-purpose I/O port, port 7 also functions as follows.
Writing 1 in the corresponding bit of P7FC, P7FC2 enables the respective functions.
Resetting resets the P7FC, P7FC2 to 0, and sets all bits to input ports.

Port 70 is a general-purpose I/O port. It is also used as SCK (Clock signal for SIO
Used as OPTRX0, it is possible to logical invert by P7<P70>.
For port C1, RXD0 or OPTRX0 is used P7FC2<P70F2>.
