Second Interrupt Register (26h)
Table 45 IRQ_ENRD1 Register
Bit
Name
Int. Type
Description
7
JTEMP_high
Level
1: Junction temperature has reached supervision level
6
LSP_overcurr
Level
1: LSP output is in over-current off mode
5
HPH_overcurr
Level
1: HPH output is in over-current off mode
4
I2S_status
1: LRCK of I2S interface is present
3
I2S_changed
Status change 1: I2S LRCK clock was started or stopped, check I2S_status
2
MIC2_connect
Level
1: Microphone was connected to MIC port 2
IRQ will be released after enabling the microphone stage.
Detecting a microphone during operation has to be done by measuring the supply
current.
1
MIC1_connect
Level
1: Microphone was connected to MIC port 1
IRQ will be released after enabling the microphone stage.
Detecting a microphone during operation has to be done by measuring the supply
current.
0
HPH_connect
Level
1: Headphone was connected to HHP port
IRQ will be released after enabling the headphone output.
Detecting a headphone during operation is not possible.
The register is R/W; default value is 00h
By writing to the register the corresponding interrupt is enabled, reading the register delivers the interrupt source.

-
USB and charger de-bounce time control
00: 512ms
01: 256ms
10: 128ms
00: not defined
5
IRQ_Acthigh
-
1: IRQ is active high
0: IRQ is active low
4
IRQ_PushPull
-
1: IRQ output is push pull
0: IRQ output is open drain
3
Remote_Det2
Edge
1: Mic2 supply current got increased, Remote detection
measure Mic2 supply
current
2
Remote_Det1
Edge
1: Mic1 supply current got increased, Remote detection
measure Mic1 supply
current
1
RTC_update
Edge
1: RTC timer IRQ occured
0
ADC_EndCon
Edge
1: 8-bit ADC conversion completed
The register is R/W; default value is 00h
By writing to bit 0 to 3, the corresponding interrupt is enabled, reading these bits delivers the interrupt source.
