Notes on Registers, Operands and Addressing Modes:

Rn - Register R0–R7 of the currently selected register bank.

@Ri - Data RAM location addressed indirectly through R0 or R1.

rel - 8-bit, signed (two’s complement) offset relative to the first byte of the following instruction. Used by

SJMP and all conditional jumps.

direct - 8-bit internal data location’s address. This could be a direct-access Data RAM location (0x00–

0x7F) or an SFR (0x80–0xFF).

#data - 8-bit constant

#data16 - 16-bit constant

bit - Direct-accessed bit in Data RAM or SFR

addr11 - 11-bit destination address used by ACALL and AJMP. The destination must be within the same

2 kB page of program memory as the first byte of the following instruction.

addr16 - 16-bit destination address used by LCALL and LJMP. The destination may be anywhere within

the 8 kB program memory space.

There is one unused opcode (0xA5) that performs the same function as NOP.
