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
17.4.3, Relationship between Data Input/Output Pins
and Shift Register.
0: Standard mode (two pins are used for data input and
output)
