Ground
1. The signal should be grounded by the host.
2. These signals are required only for 16 bit accesses and not required when installed in 8 bit systems. Devices should allow
for 3-state signals not to consume current.
3. The signal should be tied to V_CC by the host.
4. The -CSEL signal is ignored by the card in PC Card modes. However, because it is not pulled up on the card in these
modes it should not be left floating by the host in PC Card modes. In these modes, the pin is normally connected by the
host to PC Card A25 or grounded by the host.
5. The signal should be held High or tied to V_CC by the host and RFU is Reserved for Future Use.
