Chapter 3 Programming

The General Purpose I/O (GPIO) pin assignments for the SCSI Controller are shown in the table below. A 1x4 switch (S1) is provided to configure GPIO pins 2 and 3. The factory default setting shall be for Ultra-Speed and Ultra-Wide SCSI.

Table 3-1. GPIO Pin Assignments

GPIO Pin	Direction	Level	Usage
GPIO1_MASTER_l	output	1	SCSI LED; SCSI is not MASTER.

		0	SCSI is MASTER.

GPIO2	input	1	SCSI speed; selectable by switch S1.
			S1:1 OFF selects Ultra

		0	S1:1 ON selects FAST (default).

GPIO3	input	1	SCSI bus width; selectable by switch S1.
			S1:2 in OFF selects Wide-SCSI.

		0	S1:2 in ON selects Narrow-SCSI.

0, 4, 5, 6, 7, 8	-	-	Not used.

Table 3-2. SCSI Speed/Width Settings Using GPIO2:[1,2]

SCSI Type	Width	Speed
FAST SCSI	Narrow (8 bit)	10MB/second

FAST SCSI	Wide (16 bit)	20MB/second

Ultra SCSI	Narrow (8 bit)	20MB/second

Ultra SCSI	Narrow (16 bit)	40MB/second

SW1-P1 controls GPIO2 (Ultra/FAST SCSI) and SW1-P2 controls GPIO3 (Wide/Narrow SCSI bus. SW1-P3 and SW1-P4 are No Connect. Select the SCSI characteristics of your configuration according to the following table:

Width of Bus	Ultra (P1 OFF)	Fast (P1 ON)
Wide (16-bit) SCSI bus (P2 OFF)	40MB/second	20MB/second

Narrow (8-bit) SCSI bus (P2 ON)	20MB/second	10MB/second
