9.4 Addressing Mode
The GMS81C1404 and GMS81C1408 uses six addressing
modes;
Register addressing
Immediate addressing
Direct page addressing
Absolute addressing
Indexed addressing
Register-indirect addressing
(1) Register Addressing
Register addressing accesses the A, X, Y, C and PSW.
(2) Immediate Addressing
→
#imm
In this mode, second byte (operand) is accessed as a data
immediately.
Example:
0435
ADC
#35H
E45535
LDM
35H,#55H
(3) Direct Page Addressing
→
dp
In this mode, a address is specified within direct page.
Example;
C535
LDA
35H
;A
←
RAM[35H]
(4) Absolute Addressing
→
!abs
Absolute addressing sets corresponding memory data to
Data, i.e. second byte(Operand I) of command becomes
lower level address and third byte (Operand II) becomes
upper level address.
With 3 bytes command, it is possible to access to whole
memory area.
ADC, AND, CMP, CMPX, CMPY, EOR, LDA, LDX,
LDY, OR, SBC, STA, STX, STY
Example;
0735F0
ADC
!0F035H
