Signal assignment on the interface connector

Signal
[I/O]
I Reset signal from the host. This signal is low active and is
asserted for a minimum of 25 s during power on. The device has
a 10 k pull-up resistor on this signal.
I/O Sixteen-bit bi-directional data bus between the host and the
device. These signals are used for data transfer
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.
