16.3.3 Transmit Data Register (SITDR)
SITDR is a 32-bit write-only register that specifies the SIOF transmit data.
SITDR is initialized by the conditions specified in section 23, List of Registers, or by a transmit
reset caused by the TXRST bit in SICTR.
SITDR is initialized in module stop mode.

Left-Channel Transmit Data
Specify data to be output from the SIOFTxD pin as left-
channel data. The position of the left-channel data in
the transmit frame is specified by the TDLA bit in
SITDAR.
• These bits are valid only when the TDLE bit in
SITDAR is set to 1.

Right-Channel Transmit Data
Specify data to be output from the SIOFTxD pin as
right-channel data. The position of the right-channel
data in the transmit frame is specified by the TDRA bit
in SITDAR.
• These bits are valid only when the TDRE bit and
TLREP bit in SITDAR are set to 1 and cleared to 0,
respectively.
