ERROR STATUS REGISTER (0x02)
Note that the error bits are sticky bits that are not cleared by the hardware. This means that the software must
clear the register (write zeroes) and then read them to determine if there are any persistent errors.

SYSTEM CONTROL REGISTER 1 (0x03)
System control register 1 has several functions:
Bit D7:
If 0, the dc-blocking filter for each channel is disabled.
If 1, the dc-blocking filter (–3 dB cutoff <1 Hz) for each channel is enabled (default).
Bit D5:
If 0, use soft unmute on recovery from clock error. This is a slow recovery.
If 1, use hard unmute on recovery from clock error (default). This is a fast recovery.
Bit D3:
If 0, clock autodetect is enabled (default).
If 1, clock autodetect is disabled.
Bit D2:
If 0, soft start is enabled (default).
If 1, soft start is disabled.
Bits D1–D0: Select de-emphasis
