[I/O]

[Description]

RESET–

I

Reset signal from the host. This signal is low active and is

 

 

asserted for a minimum of 25 μs during power on. The device has

 

 

a 10 kΩ pull-up resistor on this signal.

DATA 0-15

I/O

Sixteen-bit bi-directional data bus between the host and the

 

 

device. These signals are used for data transfer

DIOW–, STOP

I

DIOW– is the strobe signal asserted by the host to write device

 

 

registers or the data port.

 

 

DIOW– shall be negated by the host prior to initiation of an Ultra

 

 

DMA burst. STOP shall be negated by the host before data is

 

 

transferred in an Ultra DMA burst. Assertion of STOP by the host

 

 

during an Ultra DMA burst signals the termination of the Ultra

 

 

DMA burst.
