Instruction set
11.1.6
148/201
Indirect indexed instructions (short, long)
This is a combination of indirect and short indexed addressing modes. The operand is
referenced by its memory address, which is defined by the unsigned addition of an index
register value (X or Y) with a pointer value located in memory. The pointer address follows
the opcode.
The indirect indexed addressing mode consists of two sub-modes:
●
●
Table 64.
Table 65.
LD
CP
AND, OR, XOR
ADC, ADD, SUB, SBC
BCP
CLR
INC, DEC
TNZ
CPL, NEG
BSET, BRES
BTJT, BTJF
SLL, SRL, SRA, RLC, RRC
SWAP
CALL, JP
Indirect indexed (short)
The pointer address is a byte, the pointer size is a byte, thus allowing 00 - 1FE
addressing space, and requires 1 byte after the opcode.
Indirect indexed (long)
The pointer address is a byte, the pointer size is a word, thus allowing 64 Kbyte
addressing space, and requires 1 byte after the opcode.
