1. For True IDE Mode, pin 9 is grounded.
2. The signal should be grounded by the host.
3. 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.
4. The signal should be tied to VCC by the host.
5. 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.
6. When the device does not operate in DMA mode, the signal should be held High or tied to VCC by the host. To ensure
proper operation with older hosts when DMA mode is disabled, the Card should ignore the –DMACK signal.

Status Register.
The Pass Diagnostic signal in the Master/Slave handshake
protocol.

The Binary Audio output from the Card. It is asserted High
as audio functions are not supported.
This input/output is the Disk Active/Slave Present signal in
the Master/Slave handshake protocol.
