LOADH addr16 Load High Data Address into DPH
Operation:
DPH = addr16(15:8)
Bits affected:
None
Opcode:
0111 0000 kkkk kkkk
Description:
This instruction loads the high 8 bits of a data
address into DPH. A skip over a loadh
instruction results in an extended skip (following
instruction also skipped).
From assembly language, a 16-bit address is
specified. The assembler takes the high 8 bits of
the address and encodes it in the instruction. The
low 8 bits are ignored.
