MIC/LINE Input Selector
“When full-differential input is used, the signal
should not be input to the pins marked by “X” in
Table 20.” was added.
Table 20 (Handling of MIC/Line Input Pins) was added.
Stereo Line Output Control Sequence
Power-down mode:
PMLO bit = “1”
PMLO bit = “0”
I
2
C Bus Control Mode
“those most significant 3-bits are fixed to zeros”
“those most significant 2-bits are fixed to zeros”
Register Definitions (Addr=0FH)
HPM bit: “When the HPM bit = “1”, (L+R)/2 signals
are output to Lch and Rch of the Headphone-Amp.
Both PMHPL and PMHPR bits should be “1” when
HPM bit is “1”.
“When the HPM bit = “1”, DAC output signal is
output to Lch and Rch of the Headphone-Amp as
(L+R)/2.”
