177 / 229 page  Production Data WM8993 w PD, November 2010, Rev 4.0 177 REGISTER ADDRESS BIT LABEL DEFAULT DESCRIPTION R16 (10h) Right ADC Digital Volume 8 ADC_VU 0 ADC Volume Update Writing a 1 to this bit will cause left and right ADC volume to be updated simultaneously 7:0 ADCR_VOL [7:0] 1100_0000 Right ADC Digital Volume 00h = MUTE 01h = -71.625dB … (0.375dB steps) EFh = +17.625dB Register 10h Right ADC Digital Volume REGISTER ADDRESS BIT LABEL DEFAULT DESCRIPTION R18 (12h) GPIO CTRL 1 15 JD2_SC_EINT 0 MICBIAS2 Short Circuit interrupt 0 = interrupt not set 1 = interrupt is set Cleared when a ‘1’ is written 14 JD2_EINT 0 MICBIAS2 Current Detect interrupt 0 = interrupt not set 1 = interrupt is set Cleared when a ‘1’ is written 13 WSEQ_EINT 0 Write Sequence interrupt 0 = interrupt not set 1 = interrupt is set Cleared when a ‘1’ is written. Note that the read value of WSEQ_EINT is not valid whilst the Write Sequencer is Busy. 12 IRQ 0 Interrupt status (IRQ) Polarity is determined by IRQ_POL This bit is read only. 11 TEMPOK_EIN T 0 Temp OK interrupt 0 = interrupt not set 1 = interrupt is set Cleared when a ‘1’ is written 10 JD1_SC_EINT 0 MICBIAS1 Short Circuit interrupt 0 = interrupt not set 1 = interrupt is set Cleared when a ‘1’ is written 9 JD1_EINT 0 MICBIAS1 Current Detect interrupt 0 = interrupt not set 1 = interrupt is set Cleared when a ‘1’ is written 8 FLL_LOCK_EI NT 0 FLL Lock interrupt 0 = interrupt not set 1 = interrupt is set Cleared when a ‘1’ is written 7 GPI8_EINT 0 GPI8 interrupt 0 = interrupt not set 1 = interrupt is set Cleared when a ‘1’ is written 6 GPI7_EINT 0 GPI7 interrupt 0 = interrupt not set 1 = interrupt is set |
