Manual System ADAM 821x Chapter 9 Instruction list
ADAM 8000 Manual CPU 821x – Rev 1.1 8-9
SP T [LW 8] Start timer; timer no. is in local data word 8.
CU C [LW 10] Start counter; counter no. is in local data word 10.
Memory-indirect, area-internal addressing
A I [LD 12]
e.g.: LP
#
22.2
T LD 12
A I [LD 12]
AND instruction; input address is in local data
double word 12 as pointer.
A I [DBD 1] AND instruction; input address is in data double
word 1 of the DB as pointer.
A Q [DID 12] AND instruction; output address is in data double
word 12 of the instance DB as pointer.
A Q [MD 12] AND instruction; output address is in bit memory
double word 12 as pointer.
Register-indirect, area-internal addressing
A I [AR1,P
#
12.2]
AND instruction; input address is calculated
"pointer value in address register 1 + pointer
P
#
12.2".
Register-indirect, area-crossing addressing
For the area-crossing, register indirect addressing the address needs an
additional range-ID in the Bits 24-26. The address is in the address
register.
Range-ID Binary code hex. Area
P 1000 0 000 80 Periphery area
I 1000 0 001 81 Input area
Q 1000 0 010 82 Output area
M 1000 0 011 83 Bit memory area
DB 1000 0 100 84 Data area
DI 1000 0 101 85 Instance data area
L 1000 0 110 86 Local data area
VL
1000 0 111
87 Preceding local data area
(access to the local data of
the calling block)
L B [AR1,P
#
8.0]
Load byte in ACCU1; the address is calculated
"pointer value in address register 1
+ pointer P
#
8.0".
A [AR1,P
#
32.3]
AND instruction; operand address is calculated
"pointer value in address register 1
+ pointer P
#
32.3".
Addressing via parameters
A parameter The operand is addressed via the parameter.
