EAPD data Enable
EAPD data output on EAPD when bit D11 = 1
EAPD data input from pin when bit D11 = 0
Bit not used, should read back 0
EAPD Pin Enable
0 = EAPD configured as input pin
1 = EAPD configured as output pin
Bit not used, should read back 0
Interrupt disable option.
Interrupts cleared by writing a 1 to I4 (Reg24h:D15)
0 = will clear both SENSE and GPIO interrupts
1 = will only clear SENSE interrupts. GPIO interrupts will have to be cleared in
Reg54h.
GPIO ACCESS
0 = ACLINK access from GPIO Pads
1 = ACLINK access from GPIO Register 54h
0 = GPIO0/1 access via Reg54h when GPIO is set as an output, for input Slot12
data will be 0h.
1 = GPIO0/1 access via Slot 12 when GPIO is set as an output, for inputs
Reg54h will not be updated.
This can only be used if a modem CODEC is not present in the system and using
Slot12.
