Addressing Mode
Notes on instruction set and address modes:
Rn
Register R7-R0 of the currently selected register bank.
direct
8-bits internal data location’s address. This could be internal DATA RAM location (0-127) or a
SFR [i.e., I/O port, control register, status register, etc. (128-255)]
@Ri
8-bits RAM location addressed indirectly through register R1 or R0 of the actual register bank
#data
8-bits constant included in the instruction
#data16
16-bits constant included in the instruction
addr11
11-bits destination address. Used by ACALL and AJMP. The branch can be anywhere within the
same 2 Kbytes page of program memory as the first byte of the following instruction.
rel
Signed (2’s complement) 8-bits offset byte. Used by SJMP and all conditional jumps. Range is
-128 to +127 bytes relative to first byte of the following instruction.
bit
Direct addressed bit in internal data RAM or SFR
