loads Working Register R10 with the value 4Fh. The contents of Working
Register R0 and Register 2Ch are not affected.
Example
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 contents of Working Registers R0 and R10
are unaffected by the load.
