Escaped Mode Addressing
For the LDX instruction, Escaped Mode Addressing can only be used with opcodes
E8H
and
. Address mode ER for the source or destination can specify a Working Register
E9H
with 4-bit addressing.
If the high byte of the source or destination address is
(11101110B), a Working Regis-
EEH
ter is inferred. For example, the operand
selects Working Register R3. The full 12-
EE3H
bit address is given by {RP[3:0], RP[7:4], 3H}.
To access Registers on Page EH (addresses
to
), set the Page Pointer, RP[3:0],
E00H
EFFH
to
and set the Working Group Pointer, RP[7:4], to the desired Working Group.
