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.
