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. 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. C141-E069-02EN 5 - 3
