STPS bit (Selection of the serial clock counter stop condition)
The serial operation stops when it becomes the stop position of a serial counter. There are two types of serial
counters, the serial output counter and the serial input counter. The stop condition is switched between the output and
input counters.

mode is selected.
Note:
This bit is reset to "0" after a system reset.
SWENA bit (Serial wait enable)
This control bit is effective only when the 2-wired mode is selected. usually, set this bit to "1" when the 2-wired
mode is selected.
If serial wait is enabled in the 2-wired mode, the SCK is outputted at the "L" level and becomes the clock wait
state and the serial clock is suspended when the serial output counter (OCT0~3) becomes "F" (HEX).
