Notes on Registers, Operands and Addressing Modes:
Rn - Register R0-R7 of the currently selected register bank.
@Ri - Data RAM location addressed indirectly through register R0-R1
rel - 8-bit, signed (two’s compliment) 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
#data 16 - 16-bit constant
bit - Direct-addressed bit in Data RAM or SFR.
addr 11 - 11-bit destination address used by ACALL and AJMP. The destination must be within the same 2K-
byte page of program memory as the first byte of the following instruction.
addr 16 - 16-bit destination address used by LCALL and LJMP. The destination may be anywhere within the
64K-byte program memory space.
There is one unused opcode (0xA5) that performs the same function as NOP.
