Master/Slave Device Select
Selects that this module is used in master mode or
slave mode. When master mode is selected, transfer
clocks are output from the SSCK pin. When the CE bit
in SSSR is set, this bit is automatically cleared.

Bidirectional Mode Enable
Selects that both serial data input pin and output pin are
used or one of them is used. However, transmission
and reception are not performed simultaneously when
bidirectional mode is selected. For details, section
16.4.3, Relationship between Data Input/Output Pins
and Shift Register.
0: Standard mode (two pins are used for data input and
output)
1: Bidirectional mode (one pin is used for data input and
output)
