MSB bit (Selection of the order of serial data bits)
This control bit controls the arrangement of serial data input/output data. Select whether data input/output started
from the most or the least significant bit respectively.
For the serial interface, serial data specified by the serial counter is inputted and outputted. The MSB bit controls
the serial counter to count up or down. When the MSB bit is set to "0", the serial counter counts up. When the MSB
bit is set to "1", the serial counter counts down.

Note: Serial data corresponding to the serial output counter is outputted to the serial output pin. The
state of the serial input pin corresponding to the serial input counter is stored in the serial input
data at the edge.
Note: Input and output serial counters have up and down edges reverse to each other.
Note: If any serial input/output data not present in the serial counter is designated, the output will be
"L" and the input will be "don't care".
Note: This bit is reset to "0" after a system reset.
