[bit8] FRUN : Output Mode of Frame Synchronous Signal
Bit
Description
0
Burst mode
When I2Sn_OPRREG:START bit is "1", frame synchronous signal is output according to
I2Sn_OPRREG:TXENB, I2Sn_OPRREG:RXENB, and transmission/reception FIFO conditions.
When I2Sn_OPRREG:START bit is "0", frame synchronous signal is not output.
1
Free-running mode
When I2Sn_OPRREG:START register is "1", frame synchronous signal proceeds free-running with the set
frame rate.
When I2Sn_OPRREG:START bit is "0", frame synchronous signal is not output.
[bit7] MSLB : Shifting Order
Word bit's shift order is set.
Bit
Description
0
Shift starts from MSB of the word
1
Shift starts from LSB of the word
