“When full-differential input is used, the signal
should not be input to the pins marked by “X” in
Table 20.” was added.
Power-down mode:
PMLO bit = “1”
“those most significant 3-bits are fixed to zeros”
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”.
