Description
Always write as 0 if writing to this register.
When set to 1, all slew parameters ramp to zero. It is
recommended to set this
bit to 1 prior to downloading a new program to reduce any risk of
pops or clicks
on the output.
0b = unmuted
1b= muted
Always write as 0 if writing to this register.
Used to select the MCLKI pin frequency.
00b = 512 × frequency sample (FS) (24.576 MHz)
01b = 256 × FS (12.288 MHz)
10b = 128 × FS (6.144 MHz)
11b = 64 × FS (3.072 MHz)
Used to select the source for SRC2 channel A.
00b = SDIN0
01b = SDIN1
10b = SDIN2
11b = SDIN3
Used to select the source for SRC1.
00b = SDIN0
01b = SDIN1
10b = SDIN2
11b = SDIN3
Used to enable SRC2 Channel A.
0b − disabled
1b − enabled
Used to enable SRC1 Channel A.
0b = disabled
1b = enabled
When set to 1, the ADAV4601 enters standby mode.
0b = disable standby or not in standby
1b = enable standby or not in standby
Set to 1 to enable the audio processor.
0b = disabled
1b = enabled
Globally powers up all parts of the device. If read back, it indicates
the status of
the global power-up.
0b = use power management register
1b = global power-up
