Section 15 Serial I/O with FIFO (SIOF)
It also contains a bit used to select LSB first or MSB first when transmitting and receiving to
match the connected codec, as well as a bit for controlling the LSB for transmitted primary data
and control data.
SIFCR is initialized to H'0000 by a reset.
Note that the TE and RE bits in SICTR must be cleared to 0 before changing the values of bits 11
to 10 and 7 to 0 (TRMD, LM, RFWM3 to RFWM0, TFWM3 to TFWM0).
Bit 15 to 12—Reserved: These bits are always read as 0. The write value should always be 0.
Bit 11—Transfer Mode (TRMD): Controls the LSB (bit 0) for transmitted primary data and
control data.
Note: If the TRMD bit is set to 1, in SICTR the TM bit (STS pin input) should be cleared to 0, the
Bit 10—LSB/MSB First Select (LM): Used to select LSB first or MSB first for transmitting and
receiving.
Note: This bit must be cleared to 0 if the TRMD bit is set to 1.
Bit 9—Receive FIFO Data Register Reset (RFRST): Invalidates the primary receive data in
SIRDR and resets it to empty status. Also initializes the RERR and RDRF bits in SISTR.
Note that SICTR is not initialized, so receiving continues if the RE bit is set to 1.

SE bit (interval mode) set to 1, and the LM bit (transmit/receive MSB format) cleared to 0.
The sync signal output from the connected codec should be input to pins STS and SRS.
The serial clock output from the connected codec should be input to pins STCK and SRCK.
Reset status persists while this bit is set to 1. Clear this bit to 0 to cancel reset status.
Description
Value stored in SITDR is always transmitted as LSB of primary data
LSB of primary data is always transmitted as 0
However, the LSB is 1 when the primary data immediately precedes control
data
