SORES2[1:0] - Resolution of the output data on SDOUT
00 - 24-bit resolution.
01 - 20-bit resolution.
10 - 18-bit resolution.
11 - 16-bit resolution
SOFSEL2[1:0] - Format of the output data on SDOUT
00 - Left-Justified
01 - I²S
10 - Right-Justified (Master mode only)
11 - AES3 Direct. Direct copy of the received NRZ data from the AES3 receiver including C, U, and V bits.
The time slot occupied by the Z bit is used to indicate the location of the block start. Only valid if serial port
source is the AES3-compatible receiver.
11.14 Receiver Error Unmasking (0Eh)
RECEIVER ERROR MASK[7:0]
The bits[7:0] in this register serve as masks for the corresponding bits of the Receiver Error Register. If a
mask bit is set to 1, the error is unmasked, meaning that its occurrence will appear in the receiver error reg-
ister, will affect RERR[6:0], will affect the RERR interrupt, and will affect the current audio sample according
to the status of the HOLD bit. If a mask bit is set to 0, the error is masked, meaning that its occurrence will
not appear in the receiver error register, will not affect the RERR pin, will not affect the RERR interrupt, and
will not affect the current audio sample. The CCRC and QCRC bits behave differently from the other bits:
they do not affect the current audio sample even when unmasked. If QCRC, CCRC, CONF, BIP, or PARM
are unmasked, and RERRM in register 0Fh is unmasked, then RERR[1:0] should be set to “Rising Edge
Active” in the Interrupt Mode register (register 10h). This register defaults to 00h.
