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.
Warning
Before removing or
installing any equipment
in the PC-workstation
computer, turn off the
power and disconnect the
power cord.
