Sample Usage
If Working Register Pair R6 and R7 contain the value 30A2h and Pro-
gram Memory location 30A2h contains the value 22h , the following
statement loads the value 22h into Working Register R2:
LDC R2, @RR6

Object Code: C2 26
The value of Program Memory location 30A2h is unchanged by the load.
If Working Register R3 contains the value A5h , Working Register Pair R8
and R9 contain the value 2A72h, and Program Memory location 2A72h
contains the value 42h , the following statement loads the value 42h into
Register A5h :
LDC @R3, @RR8

Object Code: C5 38
The value of Program Memory location 2A72h is unchanged by the load.
If Working Register R2 contains the value 22h , and Working Register
Pair R6 and R7 contains the value 10A2h , the following statement loads
the value 22h into Program Memory location 10A2h :
LDC @RR6, R2

Object Code: D2 26
The value of Working Register R2 is unchanged by the load.
