Note: 1 These signals are required only for 16-bit access and are not required when
installed in 8-bit systems. Devices should allow for 3-state signals not to
consume current.
2
: Should be grounded by the host system.
3
: Should be tied to VCC by the host system.
4
: The -CSEL signal is ignored by the card in PC Card moudes. However,
because it is not pulled up on the card in thses modes, it should not be left
oating by the host in PC card modes. In these modes, the pin should be
connected by th host to PC card A25 or grounded by the host.
5
: If DMA operations are not used, the signal should be held high or tied to VCC
by the host. For proper operation in older hosts: while DMA operations are not
active, the card shall ignore the signal, including a oating condition.
