General-Purpose Strobe: Connect
A_GPSTB to pin 43 and B_GPSTB to
pin 57 on PC Card socket. This pin can
be used with external logic to sense
pins VS1 and VS2 of the socket. It is
only available on the PD6722.
This status input is used to detect 5 V/
3.3 V on PCMCIA pin 57.
This output is used to enable the socket
