Description
Reserved
This bit is always read as 0. The write value should
always be 0.
Selects transfer mode from SSU mode and clock
synchronous mode.
0: SSU mode
1: Clock synchronous mode
Software Reset
Setting this bit to 1 forcibly resets the SSU internal
sequencer. After that, this bit is automatically cleared.
The ORER, TEND, TDRE, RDRF, and CE bits in SSSR
and the TE and RE bits in SSER are also initialized.
Values of other bits for SSU registers are held.
To stop transfer, set this bit to 1 to reset the SSU
internal sequencer.
Reserved
These bits are always read as 0. The write value should
always be 0.

00: 8 bits
01: 16 bits
10: 32 bits
