Table 77.
Immediate
Immediate instructions have 2 bytes, the first byte contains the opcode, the second byte
contains the operand value.
Table 78.
Direct
In Direct instructions, the operands are referenced by their memory address.
The direct addressing mode consists of two submodes:
Direct (Short)
The address is a byte, thus requires only 1 byte after the opcode, but only allows 00 - FF
addressing space.
Direct (Long)
The address is a word, thus allowing 64 Kbyte addressing space, but requires 2 bytes after
the opcode.
Indexed (No Offset, Short, Long)
In this mode, the operand is referenced by its memory address, which is defined by the
unsigned addition of an index register (X or Y) with an offset.
The indirect addressing mode consists of three submodes:
SLL, SRL, SRA, RLC, RRC
SWAP
LD
CP
BCP
AND, OR, XOR
ADC, ADD, SUB, SBC
