[Bits 5 and 4] MC1 and MC0: Mode control
Bits 5 and 4 are used to select the transfer mode (data length).
[Bit 3] SMDE:
[Bit 1] SCKE: SCLK enable
When 1 is written at bit 1, the UART serial clock output pin is switched to
the port to output an external synchronous clock pulse.
If the mode in which a synchronous clock pulse is input from the outside is
set by the CS1 and CS0 bits of the SRC register, the value can also be
read from the port as the input pin.
In the external clock input mode, set this bit to 0.
This bit is valid when the RSEL bit of the SMC2 is 0.
[Bit 0] SOE: Serial output enable
When 1 is written at bit 0, the port is switched to the UART serial data output
pin to enable serial data output.
This bit is valid when the RSEL bit of the SMC2 is 0.

Functions as general-purpose input/output port that does not

When the port is set to input (DDR = 0), it also functions as a
serial clock input pin.
