Table 54 Description of the mnemonics in the Instruction set

MNEMONIC

DESCRIPTION

Data addressing modes

Working registers R0 to R7.

direct

128 internal RAM locations and any special function register (SFR).

@Ri

Indirect internal RAM location addressed by register R0 or R1 of the actual register bank.

#data

8-bit constant included in instruction.

#data 16

16-bit constant included as bytes 2 and 3 of instruction.

bit

Direct addressed bit in internal RAM or SFR.

addr16

16-bit destination address. Used by LCALL and LJMP. The branch will be anywhere within the

64 kbytes program memory address space.

addr11

111-bit destination address. Used by ACALL and AJMP. The branch will be within the same 2 kbytes

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

rel

Signed (two's complement) 8-bit offset byte. Used by SJMP and all conditional jumps. Range is

−128 to + 127 bytes relative to ﬁrst byte of the following instruction.

Hexadecimal opcode cross-reference

8, 9, A, B, C, D, E and F.

•

1, 3, 5, 7, 9, B, D and F.

♦

0, 2, 4, 6, 8, A, C and E.
