Jumper; Counter/Timer; Counter; Fig. 9-4: Selection Of The Interrupt Line Through Jumper Field J4 - Addi-Data ADDINUM PA 1500 Technical Description

Functions of the board
Possible interrupt sources :
Event 1 has occurred (input 1-8),
-
Event 2 has occurred (input 9-14),
-
Counter/Timer 1 has run down
-
Counter/Timer 2 has run down
-
Counter/Timer 3 has run down
-
Watchdog has run down, the outputs are reset,
-
Voltage error (the external voltage supply has dropped below 5 V),
-
Short-circuit error, overtemperature error.
-
The interrupt source information are available on the user program through
an interrupt routine (See API functions: i_PA1500_SetBoardIntRoutineXX
and i_PA1500_ResetBoardIntRoutine.
An event indicates a change of status (level):
on an input (ex. "0"-->"1")
-
or on several inputs if a logic has been defined between the inputs.
-
Running-down: if the counter changes from 1

Jumper

♦ Select a free interrupt line on the PC bus with jumper field J4 (See 5.1.2).

Counter/timer

On the board PA 1500 three 16-bit counters/timers are available in the
component Z8536 (downwards counting). Each counter/timer can be
programmed by software.
If the component Z8536 operates as a counter, the corresponding inputs are
used as follows:

9.5.1 Counter

Counter 1:
Counter 2:
Counter 3
38
Input 14 signal input.
Input 10 signal input
Input 11 can be used as a "trigger" function
Input 12 can be used as a "gate" function.
Input 15 signal input
Input 16 can be used as a "gate" function.
