8.4 Addressing Mode
The GMS800 series MCU 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
When G-flag is 1, then RAM address is defined by 16-bit
address which is composed of 8-bit RAM paging register
(RPR) and 8-bit immediate data.
Example: G=1
E45535
LDM
35H,#55H
(3) Direct Page Addressing
→
dp
In this mode, a address is specified within direct page.
Example; G=0
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
;A
←
ROM[0F035H]
The operation within data memory (RAM)
ASL, BIT, DEC, INC, LSR, ROL, ROR
Example; Addressing accesses the address 0135
