Frame active level
0 = active high
1 = active low
RX-FIFO MSB extension
0 = fill 0 in redundant MSBs of RX-FIFO
1 = non-implement
Word length = SLEN[0:4] + 1.
The word length supported by SSI is from 1 to 32 bits.
SLEN[0:4] configure TX/RX also.
if SLEN[0:4] <= 15,
if 15 < SLEN[0:4] <= 31, FIFO will be configured as 24x32.
0 = Slave mode enable. SYNC, SCLK are inputs.
1 = Master mode enable. SYNC, SCLK are outputs.
0 = Short framing
Words per frame = WPF[0:3] + 1. (max. 16 words/frame)
The first data will be available on the next SCLK cycle as SYNC is active. In this mode,
The first data will be available on the same SCLK cycle as SYNC is active. In this mode,
SYNC width is 1 SLEN.
SYNC width is 1 SCLK.
