Description
Serial Oversampling Clock Division Ratio
These bits define the division ratio between
oversampling Clock (SSI_CLK) and the serial bit clock.
These bits are ignored if SCKD = 0.
The Serial Bit Clock is used for the shift register and is
provided on the SSI_SCK pin.
000: (Serial bit clock frequency = oversampling clock frequency/1)
001: (Serial bit clock frequency = oversampling clock frequency/2)
010: (Serial bit clock frequency = oversampling clock frequency/4)
011: (Serial bit clock frequency = oversampling clock frequency/8)
100: (Serial bit clock frequency = oversampling clock frequency/16)
101: (Serial bit clock frequency = oversampling clock frequency/6)
110: (Serial bit clock frequency = oversampling clock frequency/12)
111: Setting prohibited
Mute Enable
0: The SSI module is not muted
1: The SSI module is muted
Reserved
This bit is always read as 0. The write value should
always be 0.
Transmit/Receive Mode Select
0: The SSI module is in receive mode
1: The SSI module is in transmit mode
SSI Module Enable
0: The SSI module is disabled
1: The SSI module is enabled
