Description
SIOFSYNC Pin Polarity
Valid when the SIOFSYNC signal is output as
synchronous pulse in master mode.
0: Active-high
1: Active-low
Data Pin Bit Delay for SIOFSYNC Pin
Valid when the SIOFSYNC signal is output as
synchronous pulse. Only one-bit delay is valid for
transmission in slave mode.
0: No bit delay
1: 1-bit delay
Reserved
These bits are always read as 0. The write value should
always be 0. If 1 is written to these bits, the operation
cannot be guaranteed.
