DAC1 SZCMode[1:0]: Sets the soft ramp and
zero crossing detection modes by which volume
and muting changes will be implemented.
‘00’b - Immediate Change: When immediate
change is selected, all level changes will take
effect immediately in one step
‘01’b - Zero Cross: Dictates that signal level
changes, both muting and gain/attenuation, will
occur on a signal zero crossing to minimize audi-
ble artifacts. The requested level change will
occur after a timeout period
(approximately???? ms) if the signal does not
encounter a zero crossing. The zero cross func-
tion is independently monitored and imple-
mented for each channel.
‘10’b - Soft Ramp: Allows level changes, both
muting and gain/attenuation, to be implemented
by incrementally ramping, in 1/8 dB steps, from
the current level to the new level at a rate of
1/8 dB per audio sample period.
‘11’b - Soft Ramp on Zero Cross: Dictates that
signal level changes, both muting and gain/atten-
uation, will occur in 1/8 dB steps and be imple-
mented on a signal zero crossing. The 1/8 dB
level change will occur after a timeout period
(approximately??? ms) if the signal does not
encounter a zero crossing. The soft ramp on
zero cross function is independently monitored
and implemented for each channel.
Reserved
DMIC2 Enable: Specifies whether GPIO1 or Dig-
ital Mic Interface 2 is enabled.
‘0’b - GPIO1 enabled, Digital Mic 2 disabled.
‘1’b - Digital Mic 2 enabled, GPIO1 disabled.
DMIC1 Enable: Specifies whether GPIO0 or Dig-
ital Mic Interface 1 is enabled.
‘0’b - GPIO0 enabled, Digital Mic 1 disabled.
‘1’b - Digital Mic 1 enabled, GPIO0 disabled.
DAC3 Beep Enable: This bit allows the output
from the beep generator to be passed to DAC3.
DAC2 Beep Enable: This bit allows the output
from the beep generator to be passed to DAC2.
DAC1 Beep Enable: This bit allows the output
from the beep generator to be passed to DAC1.
