PIDE_IOW*

23

Drive I/O Write – Strobe signal for write functions. Negative edge

 

 

 

 

 

enables data from a register or data port of the drive onto the host

 

 

 

 

 

data bus. Positive edge latches data at the host.

 

 

 

GND

PIDE_IOR*

25

Drive I/O Read – Strobe signal for read functions. Negative edge

 

 

 

 

 

enables data from a register or data port of the drive onto the host

 

 

 

 

 

data bus. Positive edge latches data at the host.

 

 

 

GND

26

Ground

PIDE_RDY

27

I/O Channel Ready – When negated extends the host transfer cycle

 

 

 

 

 

of any host register access when the drive is not ready to respond to

 

 

 

 

 

a data transfer request. High impedance if asserted.

CBLID_P*

28

Cable ID Select – Used to detects the presence of an 80 conductor

 

 

 

 

 

IDE cable on the primary IDE channel. This allows BIOS or

 

 

 

 

 

system software to determine if is necessary to enable high-speed

 

 

 

 

 

transfer modes (DMA66 or DMA100).

PIDE_AK*

29

DMA Channel Acknowledge – Used by the host to acknowledge

 

 

 

 

 

data has been accepted or data is available. Used in response to

 

 

 

 

 

DMARQ asserted.

 

 

 

GND

30

Ground

PIDE_INTRQ

31

Drive Interrupt Request (IRQ 14)– Asserted by drive when it has

 

 

 

 

 

pending interrupt (PIO transfer of data to or from the drive to the

 

 

 

 

 

host).
