Frame Length 3 to 0
00xx: Data length is 8 bits and frame length is 8 bits.
0100: Data length is 8 bits and frame length is 16 bits.
0101: Data length is 8 bits and frame length is 32 bits.
0110: Data length is 8 bits and frame length is 64 bits.
0111: Data length is 8 bits and frame length is 128 bits.
10xx: Data length is 16 bits and frame length is 16 bits.
1100: Data length is 16 bits and frame length is 32 bits.
1101: Data length is 16 bits and frame length is 64 bits.
1110: Data length is 16 bits and frame length is 128 bits.
1111: Data length is 16 bits and frame length is 256 bits.
Note: When data length is specified as 8 bits, control
data cannot be transmitted or received.
x: Don't care
7 TXDIZ 0 R/W SIOFTxD Pin Output when Transmission is Invalid*
0: High output (1 output) when invalid
1: High-impedance state when invalid
Note: Invalid means when disabled, and when a slot that
is not assigned as transmit data or control data is
being output.
6 0 R Reserved
This bit is always read as 0. The write value should
always be 0.
5 SYNCAC 0 R/W SIOFSYNC Pin Polarity
This bit is valid in master mode.
0: Active-high
1: Active-low
4 SYNCDL 0 R/W Data Pin Bit Delay for SIOFSYNC Pin
Only 1-bit delay is valid in slave mode.
0: No bit delay
1: 1-bit delay
