www.ti.com Addressing Modes
3.3.3 Symbolic Mode
The symbolic mode is described in Table 3-6.
Table 3-6. Symbolic Mode Description
Assembler Code Content of ROM
MOV EDE,TONI MOV X(PC),Y(PC)
X = EDE – PC
Y = TONI – PC
Length: Two or three words
Operation: Move the contents of the source address EDE (contents of PC + X) to the destination address TONI (contents of
PC + Y). The words after the instruction contain the differences between the PC and the source or destination
addresses. The assembler computes and inserts offsets X and Y automatically. With symbolic mode, the program
counter (PC) is incremented automatically so that program execution continues with the next instruction.
Comment: Valid for source and destination
Example:
MOV EDE,TONI ;Source address EDE = 0F016h
;Dest. address TONI = 01114h
