3 MUEN 0 R/W Mute Enable
0: This module is not muted.
1: This module is muted.
Note: When this module is muted, the value of outputting
serial data is re-written to 0 but data transmission is
not stopped. Write dummy data to the SSIFTDR not
to generate a transmit underflow because the
number of data in the transmit FIFO is decreasing.
2 0 R Reserved
The read value is undefined. The write value should
always be 0.
1 TEN 0 R/W Transmit Enable
0: Disables the transmit operation.
1: Enables the transmit operation.
