[bit 1] SCKE (SCLK enable):
This bit is used to specify whether to use the SCK0 pin as a clock input pin or clock output pin in CLK
synchronous mode (mode 2) communication.
Set '0' in this bit in CLK asynchronous mode or external clock mode.
0
The SCK0 pin is used as a clock input pin.
1
The SCK0 pin is used as a clock output pin.
Note: To use the SCK0 pin as a clock input pin, an external clock source must have been
selected.
[bit 0] SOE (Serial output enable):
This bit is used to specify whether the external pin is used as a serial output pin (SOT0) or I/O port pin.
0
The external pin is used as a general-purpose I/O port pin.
1
The external pin is used as a serial data output (SOT0) pin.
