RANGE

The PC104-CTR BASE switch may be set for address in the range of 000-3F8 so it

should not be hard to find a free address area for you PC104-CTR. Once again, if you

are not using IBM prototype cards or some other board which occupies these

addresses, then 300-31Fh are free to use.

Address not specifically listed, such as 390-39F, are free.

2.2 INTERRUPT LEVEL SELECT

A single interrupt input (IR INPUT) allows you to initiate an interrupt service routine

with an external pulse. The interrupt level is selected via software.

2.3 CLOCK SOURCE SELECT

The source of the pulses supplied to each of the AM9513 chips for timing operations

is individually programmable. The on-board 1 MHz or 5 MHz source may be

selected or an external source (EXT SRCx) may be selected.
