All Rights Reserved. www.austriamicrosystems.com Table 90 Fifth Interupt Register Name Base Default IRQ_ENRD_4 2-wire serial 0x00 Fifth Interrupt Register Offset: 27h Please be aware that writing to this register will enable/disable the corresponding interrupts, while with reading you get the actual interrupt status and will clear the register at the same time. It is not possible to read back the interrupt enable/disable settings. This register is reset at a DVDD-POR. Bit Bit Name Default Access Bit Description 7:6 T_DEB<1:0> 00 R/W Sets the USB and Charger connect de-bounce time: 00: 340ms 01: 170ms 10: 85ms 11: 4ms 5 XIRQ_AH 0 R/W Sets the active output state of the XIRQ line: 0: IRQ is active low 1: IRQ is active high 4 XIRQ_PP 0 R/W Sets the XIRQ output buffer type: 0: IRQ output is open drain 1: IRQ output is push pull 0 W Microphone 2 remote key press detection interrupt setting 0: disable 1: enable 3 REM2_DET (edge) x R Microphone 2 remote key press detection interrupt reading 0: no key press detected 1: Microphone 2 supply current got increased, remote key press detected -> measure MICS supply current 0 W Microphone 1 remote key press detection interrupt setting 0: disable 1: enable 2 REM1_DET (edge) x R Microphone 1 remote key press detection interrupt reading 0: no key press detected 1: Microphone 1 supply current got increased, remote key press detected -> measure MICS supply current 0 W RTC timer interrupt setting 0: disable 1: enable 1 RTC_UPDATE (edge) x R RTC timer interrupt reading 0: no RTC interrupt occurred 1: RTC timer interrupt occurred. Selecting minute or second interrupt can be done via RTCT register (29h) 0 W ADC end of conversion interrupt setting 0: disable 1: enable 0 ADC_EOC (edge) x R ADC end of conversion interrupt reading 0: ADC conversion not finished 1: ADC conversion finished. Read out ADC_0 and ADC_1 register to get the result (2Eh & 2Fh) Revision 1v3 88 - 93 |
