 SAITCON command

・ Command

1st byte

BWO

MSBO

ISSCKO

DLYO

WSLO

2nd byte

The SAITCON command sets the serial audio interface (SAI) transmission format.

Use the same format as that of SAIRCON command.

Set this bit when the Lch-side serial audio interface (SAI) operation of the SAICH command is stopped (LEN="0") and the

Rch-side serial audio interface (SAI) operation is stopped (REN="0"). If either LEN or REN is set to "1", the entered

SAITCON command is ignored.

WSLO specifies the LRCLK polarities when transmitting.

WSLO

Description

L channel is transmitted when LRCLK is "L" level,

R channel is transmitted when LRCLK is "H" level (initial value)

L channel is transmitted when LRCLK is "H" level,

R channel is transmitted when LRCLK is "L" level

DLYO specifies whether transmit data has a 1-clock delay or not.

DLYO

Description

Serial data delay (initial value)

No serial data delay

ISSCKO specifies the BCLK pin as 32fs or 64fs.

ISSCKO

Description

32 fs (initial value)

64 fs

MSBO specifies MSB first or LSB first in the transmit data.

MSBO

Description

MSB first (initial value)

LSB first

BWO specifies the bit width for transmission.

BWO

Description

16-bit straight PCM (initial value)

8-bit straight PCM

For the transmission format, refer to the "SAI (Serial Audio Interface)" in the function description.

For the timing of inputting the SAITCON command, refer to "SAITCON command timing" in the timing chart.
