Receive Control Data Register (SIRCR)
SIRCR is a 32-bit readable/writable register that stores receive control data of the SIOF. The
setting of SIRCR is valid only when bits FL3 to FL0 in SIMDR are set to 1xxx (x: any value).

Control Channel 0 Receive Data
These bits store data received from the SIOF_RXD pin
as control channel 0 receive data. The position of the
control channel 0 data in the transmit or receive frame
depends on the value set the CD0A bit in SICDAR.
