SPPS: Speaker-amp Power-Save-Mode
0: Power Save Mode (Default)
1: Normal Operation
When the SPPS bit = “1”, the Speaker-amp is in power-save-mode and the SPP pin becomes Hi-z and SPN pin is
set to HVDD/2 voltage. When the PMSPK bit = “1”, this bit is valid. After the PDN pin changes from “L” to “H”,
the PMSPK bit is “0”, which powers down Speaker-amp
LOOP: Loopback ON/OFF
0: OFF (Default)
1: ON
When this bit is “1”, the ADC output is passed to the DAC input internally. The external input data to DAC is
ignored.
HPM: Mono output select of Headphone
0: Stereo (Default)
1: Mono.
When the HPM bit = “1”, (L+R)/2 signals are output to Lch and Rch of the Headphone-amp.
HPLM: Lch of HP-Amp output control
0: Enable output from Rch of Headphone-amp (Default)
1: Lch mono output of Headphone-amp. The PMHPR bit can be powered down at this time.
HPRM: Rch of HP-Amp output control
0: Enable output from Lch of Headphone-amp (Default)
1: Rch mono output of Headphone-amp. The PMHPL bit can be powered down at this time.
