ROM[0F035H]

The operation within data memory (RAM)
ASL, BIT, DEC, INC, LSR, ROL, ROR

Example; Addressing accesses the address 0135

regard-

less of G-flag and RPR.

ROM[135H]

(5) Indexed Addressing

X indexed direct page (no offset)

→

{X}

In this mode, a address is specified by the X register.

ADC, AND, CMP, EOR, LDA, OR, SBC, STA, XMA

Example; X=15

, G=1, RPR=01

LDA

{X}

;ACC

←

RAM[X].

X indexed direct page, auto increment

→

{X}+

In this mode, a address is specified within direct page by
the X register and the content of X is increased by 1.

LDA, STA

Example; G=0, X=35

LDA

{X}+

X indexed direct page (8 bit offset)

→

dp+X

This address value is the second byte (Operand) of com-
mand plus the data of

-register. And it assigns the mem-

ory in Direct page.

ADC, AND, CMP, EOR, LDA, LDY, OR, SBC, STA
STY, XMA, ASL, DEC, INC, LSR, ROL, ROR
