Escaped Mode Addressing

Using Escaped Mode Addressing, address modes R or IR can specify a

working register. If the destination address is prefixed by

Eh (1110b), a

working register is inferred. For example, if Working Register R12 (

Ch) is

the preferred destination operand, use

ECh as the destination operand in

the Op Code. To access registers with addresses

E0h to EFh, either set the

Working Group Pointer,

RP[7:4], to Eh or use indirect addressing.

Sample Usage

Using Escaped Mode Addressing, if Working Register R6 contains AFh,

the following statement leaves the value

00h in Working Register R6:

CLR R6



Object Code: B0 E6

If Register A5h contains the value 23h, and Register 23h contains the

value

FCh, the following statement leaves the value 00h in Register 23h:

CLR @

A5h

Object Code: B1 A5
