79 / 128 page  Production Data WM8912 w PD, Rev 4.0, September 2010 79 REGISTER ADDRESS BIT LABEL DEFAULT DESCRIPTION R127 (7Fh) Interrupt Status 10 IRQ 0 Logical OR of all other interrupt flags 9 GPIO_BCLK_EINT 0 GPIO4 interrupt 0 = interrupt not set 1 = interrupt is set Cleared when a ‘1’ is written 8 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 5 GPIO1_EINT 0 GPIO1 interrupt 0 = interrupt not set 1 = interrupt is set Cleared when a ‘1’ is written 2 FLL_LOCK_EINT 0 FLL Lock interrupt 0 = interrupt not set 1 = interrupt is set Cleared when a ‘1’ is written R128 (80h) Interrupt Status Mask 9 IM_GPIO_BCLK_EI NT 1 GPIO4 interrupt mask 0 = do not mask interrupt 1 = mask interrupt 8 IM_WSEQ_EINT 1 Write sequencer interrupt mask 0 = do not mask interrupt 1 = mask interrupt 5 IM_GPIO1_EINT 1 GPIO1 interrupt mask 0 = do not mask interrupt 1 = mask interrupt 2 IM_FLL_LOCK_EIN T 1 FLL Lock interrupt mask 0 = do not mask interrupt 1 = mask interrupt R129 (81h) Interrupt Polarity 9 GPIO_BCLK_EINT_ POL 0 GPIO4 interrupt polarity 0 = active high 1 = active low 8 WSEQ_EINT_POL 0 Write Sequencer interrupt polarity 0 = active high (interrupt is triggered when WSEQ is busy) 1 = active low (interrupt is triggered when WSEQ is idle) 5 GPIO1_EINT_POL 0 GPIO1 interrupt polarity 0 = active high 1 = active low 2 FLL_LOCK_EINT_P OL 0 FLL Lock interrupt polarity 0 = active high (interrupt is triggered when FLL Lock is reached) 1 = active low (interrupt is triggered when FLL is not locked) R130 (82h) Interrupt Debounce 9 GPIO_BCLK_EINT_ DB 0 GPIO4 interrupt debounce 0 = disabled 1 = enabled |
