Dual-Channel CardBus and PCMCIA
Operate/suspend bit. Selects which latch receives data: high = operation,
low = suspend.
Turns on VCCB when high, pulls VCCB to GND when low.
If VCCB is on, a high connects VY to VCCB, and a low connects VX to VCCB.
Puts VCCB in a high-impedance state when high. Overrides VCCBON.
Turns on VPPB when high, pulls VPPB to GND when low.
If VPPB is on, a high connects VPPB to 12INB, and a low connects VPPB to VCCB.
Puts VPPB in a high-impedance state when high. Overrides VPPBON.
Reserved for future use.
ADD7 to ADD1 provide a return address for any interrupt query. For these devices, the
return addresses are:
1010000 = Channel A, ADD = low
1010001 = Channel B, ADD = low
1010010 = Channel A, ADD = high
1010011 = Channel B, ADD = high

Indicates catastrophic (thermal or undervoltage lockout) fault when high.
Indicates VCCA overcurrent/undervoltage lockout when high.
Indicates VPPA overcurrent/undervoltage lockout when high.
Indicates VCCB overcurrent/undervoltage lockout when high.
Indicates VPPB overcurrent/undervoltage lockout when high.
Indicates dual part (single-channel devices would read 1).
