Description
The AC contents and the M(DP) contents
are exchanged.Then, the DPL contents are
decremented –1.
The contents of ROM addressed by the PC
whose low-order 8 bits are replaced with the E
and AC contents are loaded in the AC and E.

The AC contents are transferred to the E.
The AC contents and the M(DP) contents
are compared and the CF and ZF are
set/reset.
The AC contents are stored in the M(DP).

The AC contents and immediate data
I3 I2 I1 I0 are compared and the ZF and CF
are set/reset.
The DPL contents and immediate data
I3 I2 I1 I0 are compared.
The AC contents and the M(DP) contents
are exchanged.Then, the DPL contents are
incremented +1.
The AC contents and the M(DP) contents
are exchanged.
The AC contents and the M(DP) contents
are exchanged.Then, the DPH contents are
modified with the contens of(DPH)
0M2M1M0.
The M(DP) contents are loaded in the AC.
The AC contents are cleared.
