Implied the data value/data address is implicitly associated with the instruction.
Accumulator the instruction implies that the data is one of the accumulator registers.
Immediate 8-bit or 16-bit data is provided in the instruction.
Direct one-byte operand provided in the instruction specifies the memory address in page zero (0000h - 00FFh) where data is located.
Extended two-byte operand provided in the instruction specifies the memory address where data is located.
Relative one byte offset is added to the address of the next instruction (the contents of the program counter register + 2). The offset is a signed number in the range -127 - +127.
Indexed one byte operand is added to the contents of the X register, the resulting 16-bit value is a pointer to memory where data is located. The range of memory accessible is x + 0 to x + 255
InherentThe address is implied by the instruction.
