Escaped Mode Addressing
SP
@SP
The Stack Pointer contents decrement by one. The source operand contents are loaded into
the location addressed by the decremented Stack Pointer, adding a new element to the
stack.
Using Escaped Mode Addressing, address mode ER can specify a Working Register with
4-bit addressing.
If the high byte of the source or destination address is EEH (11101110B), a Working Reg-
ister is inferred. For example, the operand EE3H selects Working Register R3. The full 12-
bit address is given by {RP[3:0], RP[7:4], 3H}.
To access Registers on Page EH (addresses E00H to EFFH), set the Page Pointer, RP[3:0],
to EH and set the Working Group Pointer, RP[7:4], to the desired Working Group.
