Function
JDx(GPIOx) Status Indication in SDATA_IN
0: The status of JD0(GPIO0)/JD1(GPIO1)/JD2 and its valid tag are not indicated in SDATA_IN.
1: The status of JD0(GPIO0)/JD1(GPIO1)/JD2 and its valid tag are indicated in SDATA_IN
S/PDIFI Valid Interrupt Enable
0: Disable
S/PDIFI Lock Interrupt Enable
0: Disable
Reserved
MIC Sense Interrupt Enable
0: Disable
When the sense status bit in MX74.15 is changed, this will trigger the MIC Sense interrupt in bit0 of
SDATA_IN’s slot-12.
LINE-IN Sense Interrupt Enable
0: Disable
When the sense status bit in MX74.14 is changed, this will trigger the MIC Sense interrupt in bit0 of
SDATA_IN’s slot-12.
Reserved
JD2 Interrupt Enable (when it is used as input)
0: Disable
A low to high transaction will trigger the GPIO interrupt in bit0 of SDATA_IN’s slot-12.
JD1(GPIO1) interrupt Enable (when it is used as input)
0: Disable
A low to high transaction will trigger the GPIO interrupt in bit0 of SDATA_IN’s slot-12.
JD0(GPIO0) interrupt Enable (when it is used as input)
0: Disable
A low to high transaction will trigger the GPIO interrupt in bit0 of SDATA_IN’s slot-12.
Reserved
GPIO1 Primitiveness Control
0: Set JD1(GPIO1) as input pin
1: Set JD1(GPIO1) as output pin
GPIO0 Primitiveness Control
0: Set JD0(GPIO0) as input pin.
1: Set JD0(GPIO0) as output pin.
