MIC/LINE Input Selector
âWhen full-differential input is used, the signal
should not be input to the pins marked by âXâ in
Table 20.â was added.
Table 20 (Handling of MIC/Line Input Pins) was added.
Stereo Line Output Control Sequence
Power-down mode:
PMLO bit = â1â Ã PMLO bit = â0â
I2C Bus Control Mode
âthose most significant 3-bits are fixed to zerosâ
à âthose most significant 2-bits are fixed to zerosâ
Register Definitions (Addr=0FH)
HPM bit: âWhen the HPM bit = â1â, (L+R)/2 signals
are output to Lch and Rch of the Headphone-Amp.
Both PMHPL and PMHPR bits should be â1â when
HPM bit is â1â.
à âWhen the HPM bit = â1â, DAC output signal is
output to Lch and Rch of the Headphone-Amp as
(L+R)/2.â
Control Sequence (Clock Setup: Ext Slave Mode)
MCLK Frequency: 1024fs à 256fs
Addr=05H: Data=27H Ã 00H
Control Sequence (Clock Setup: Ext Master Mode)
MCLK Frequency: 1024fs à 256fs
Addr=05H: Data=27H Ã 00H
Control Sequence (Headphone Playback)
Digital Volume Level: 0dB Ã â8dB
Addr=0EH: Data=14H Ã 19H
