At DATTC bit = “1”, ATTL7-0 bits control both Lch and Rch attenuation level, while register values of
ATTL7-0 bits are not written to ATTR7-0 bits. At DATTC bit = “0”, ATTL7-0 bits control Lch level and
ATTR7-0 bits control Rch level.
Default: “01” (1020LRCK at Normal Speed Mode)
PGAR4-0, LMUTE, HMUTEL and HMUTER (See Table 15)
Default: “00”
0: Independent (Default)

At PGAC bit = “1”, PGL4-0 bits control both Lch and Rch attenuation level, while register values of
PGAL4-0 bits are not written to PGAR4-0 bits. At PGAC bit = “0”, PGAL4-0 bits control Lch level and
PGAR4-0 bits control Rch level.
