P3.0
SPID/RXD
If serial port is in mode 0, the pin works as the data line of the SPI
port.
If serial port is in mode 1, 2, or 3, the pin works as the RXD of the
80C32 standard.
P3.1
SPIC/TXD
If serial port is in mode 0, the pin works as the clock line of the SPI
port.
If serial port is in mode 1, 2, or 3, the pin works as the TXD of the
