Description
Card I/O isolation
Set this bit to drive CIO5 pin according to CARDIO5.
Clear this bit to drive the CIO5 pin connected to inputs according to IO_SELECT registers.
If IOSEL config doesn’t link an input to CIO5, CIO5 outputs CARDIO5 value.
Card I/O isolation
Set this bit to drive CIO4 pin according to CARDIO4.
Clear this bit to drive the CIO4 pin connected to inputs according to IO_SELECT registers.
If IOSEL config doesn’t link an input to CIO4, CIO4 outputs CARDIO4 value.
Card I/O isolation
Set this bit to drive CIO3 pin according to CARDIO3.
Clear this bit to drive the CIO3 pin connected to inputs according to IO_SELECT registers.
If IOSEL config doesn’t link an input to CIO3, CIO3 outputs CARDIO3 value.
Card I/O isolation
Set this bit to drive the CIO2, CC42, CC82 pins according to CARDIO2, CARDC42, CARDC82 respectively.
Clear this bit to drive the CIO2, CC42 and CC82 pins connected to inputs according to IO_SELECT register.
If IOSEL config doesn’t link an input to CIO2, CIO2 outputs CARDIO2 value.
Interrupt Disable of Smart Card Interface 5
Set this bit to disable interrupts from the interface 5 (the flags are set but INT pin is not driven).
Clear this bit to allow interrupts.
Interrupt Disable of Smart Card Interface 4
Set this bit to disable interrupts from the interface 4(the flags are set but INT pin is not driven).
Clear this bit to allow interrupts.
Interrupt Disable of Smart Card Interface 3
Set this bit to disable interrupts from the interface 3 (the flags are set but INT pin is not driven).
Clear this bit to allow interrupts.
Interrupt Disable of Smart Card Interface 2
Set this bit to disable interrupts from the interface 2(the flags are set but INT pin is not driven).
Clear this bit to allow interrupts.
