This register is a register setting a movement mode of SAI, and RECPLAY bit of the Record/Playback Running Control
register, please change this register in recording stop state (0x0).
MST
It appoints whether this bit uses SAI with a master mode or a slave mode.

BSWP
As for this bit, it is done byte swap I2S data with PCM format by 16bitPCM without depending on the setting of the I2S
Receiver Control/I2S Transmitter Control register at the time of setting when I set byte swap having I2S or not on the same
side of transmission and reception data and there is byte swap and sets it.
Setting
Explanation
There is no byte swap
0
(16bit data line up :15bit-8bit,7bit-0bit)
(24bit data line up :23bit-16bit,15bit-8bit,7bit-0bit)
There is byte swap
1
(16bit data line up :7bit-0bit,15bit-8bit)
(24bit data line up :7bit-0bit,15bit-8bit 23bit-16bit)

This register sets the filter function of the digital code processing ON/OFF.
If COEFSEL=0, then register level of HPF1/2EN, EQ0/1/2/3/4EN, HPF2OD is effective. If COEFSEL=1, then value of
HPF1/2ENB, EQ0/1/2/3/4ENB, HPF2ODB register becomes effective.
