Function
Extension register Write Enable
0: Disable 1: Enable
This bit enables the write function for MX68/6A/6C in page-2h.
S/PDINF-In Valid Interrupt Status (S/PDIFIN_VIS).
0: No S/PDIFI Valid Interrupt
1: S/PDIFI Valid Interrupt
S/PDIFIN_VIS= (MX76.14==1) & (S/PDIFI _V valid is changed) & (Locked)
Write 1 to clear this status bit and its interrupt.
S/PDINF-In Lock Interrupt Status (S/PDIFIN_LIS).
0: No S/PDIFI Lock Interrupt
1: S/PDIFI LOCK interrupt
S/PDIFIN_LIS = (MX76.13==1) & (S/PDIFI lock state is changed)
Write 1 to clear this status bit and its interrupt.
Reserved
JD4 Input Status
0: JD4 is driven low by external device
1: JD4 is driven high by external device
JD3 Input Status
0: JD3 is driven low by external device
1: JD3 is driven high by external device
JD1(GPIO1) Output Control
0: Drive GPIO1 low.
1: Drive GPIO1 high.
JD0(GPIO0) Output Control
0: Drive GPIO0 low.
1: Drive GPIO0 high.
Reserved
JD2 Interrupt Status (JD2_IS). (When it is used as input)
0: No JD2 Interrupt
1: JD2 Interrupt
JD2_IS = (MX76.6==1) & (JD2 transition)
Write 1 to clear this status bit.
JD1(GPIO1) Interrupt Status (GPIO1_IS). (When it is used as input)
0: No JD0(GPIO1) Interrupt
1: JD1(GPIO1) Interrupt
GPIO1_IS = (MX76.1==0) & (MX76.5==1) & (GPIO1 transition)
Write 1 to clear this status bit.
JD0(GPIO0) Interrupt Status (GPIO0_IS). (When it is used as input)
0: No JD0(GPIO0) Interrupt
1: JD0(GPIO0) Interrupt
GPIO0_IS= (MX76.0==0)&(MX76.4==1) & (GPIO0 transition)
Write 1 to clear this status bit.
