2-2 Universal Command Converter Motorola

Host Computer Interface Card

ISA expansion slots. A single PC-workstation interface card can control up to eight

command converters.

2.1.1.1 Installing the PC-Workstation’s Interface

Refer to the appropriate installation and set-up manual for your PC-workstation for

instructions on removing the system cover.

Jumper group JG1 selects the interrupt asserted on the host processor by the host interface

card when the target DSP device makes a service request (for example, by reaching a

breakpoint).

Note: The ADS software does not support interrupts. No jumper should be placed on

JG1 when used with the ADS software.

Jumper group JG2 specifies the host interface card I/O address. The host interface card

supports 16-bit I/O addresses and uses three consecutive addresses from the specified

address. The starting address may be configured, with jumper pairs A8–A15 in JG2, to

any multiple of $100, up to $FF00. Place a jumper over a pair of pins to set that address bit

to 0; remove the jumper to set the address bit to 1. Address bits A0–A7 are not decoded. In

Figure 2-2, the selected address range is $100–$102.

Note: Although the host interface card supports 16-bit addressing, the ADS software

only supports addresses $100, $200, and $300.

Once you have ensured that the selected address does not conflict with another expansion

card installed in the motherboard, you may install the host interface card. Figure 2-2

illustrates the physical locations of JG1 and JG2.
