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.
FS2-0: Sampling frequency modes (Table 3, Table 7)
Default: “000” (fs=44.1kHz)
