UM001604-0108 Instruction Description
194
Example 11
If Working Register R0 contains the value
08h
and Register
2Ch
(
24h
+
08h
=
2Ch
) con-
tains the value
4Fh
, the statement:
LD R10, 24h(R0)
Op Code: C7 A0 24
loads Working Register R10 with the value
4Fh
. The contents of Working Register R0 and
Register
2Ch
are not affected.
Example 12
If Working Register R0 contains the value
0Bh
and Working Register R10 contains
83h
the statement:
LD F0h(R0), R10
Op Code: D7 A0 F0
loads the value
83h
into Register
FBh
(
F0h
+
0Bh
=
FBh
). Because this is the Interrupt
Mask Register, the LOAD statement has the effect of enabling IRQ0 and IRQ1. The con-
tents of Working Registers R0 and R10 are unaffected by the load.
