EFKA AB286A5400 23
11 Interrupt Control
Parameter 0F - Interrupt Control Byte
Bit 0 = 1 Receive interrupt line 1 (IRQ1)
Bit 1 = 1 Transmit interrupt line 1
Bit 2 = 1 Receive interrupt line 2 (IRQ2)
Bit 3 = 1 Transmit interrupt line 2
Bit 5/4 = 00 IRQ1 delay with counter 1 (parameter 4C)
= 01 IRQ1 delay with counter 1, then with timer 1 (parameter 4D)
= 10 IRQ1 delay with timer 1, then with counter 1
= 11 IRQ1 delay with timer 1
Bit 7/6 = 00 IRQ2 delay with counter 2 (parameter 4E)
= 01 IRQ2 delay with counter 2, then with timer 2 (param eter 4F)
= 10 IRQ2 delay with timer 2, then with counter 2
= 11 IRQ2 delay with timer 2
If bits 0 - 3 of this control byte are set, the next command arriving and the interrupt request will be linked.
Example 1: Interrupt control byte = 00110001 = Bit 0 - Receive interrupt line 1 (IRQ1)
= Bit 4/5 - Delay with timer 1 (IRQ1)
In case of a subsequent data link establishment, e.g. in order to stop the drive in position 1, this command
will be executed only after IRQ1 has become active and after the delay with timer 1.
Example 2: Interrupt control byte = 11001000 = Bit 3 - Transmit interrupt line 2 (IRQ2)
= Bit 6/7 - Delay with timer 2 (IRQ2)
In case of a subsequent RTS for a status byte, the update of a certain bit within the status byte will be
signalled by setting IRQ2 after the delay with timer 2. An interrupt is triggered by the status modification of a
bit in the status byte if it is selected in the following manner:
Group No. Description Bit 7 6 5 4 3 2 1 0
0 02 Status Byte 1 PSYN NPE RDY P01 P02 POE DZE STP
The interrupt is to be triggered, when the drive is in position 1. This is done by a data link establishment for status byte bit
4. The master transmits text “
02 = 00010000“ and hereby determines that an interrupt is to be triggered, when bit 4 changes
from 0 to 1.
If an interrupt is to be triggered, when the drive is no longer in position 1, the master transmits text “
02=11101111“ . The
interrupt is triggered, when bit 4 changes from 1 to 0.
Note
Only one interrupt per line can be enabled by the master control !
The pulse length of an interrupt is 100µs!
