[signal]	[I/O]	[Description]
RESET–	I	Reset signal from the host. This signal is low active and is asserted
		for a minimum of 25 µ s 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.
