DESCRIPTION
Data addressing modes
Rr
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 rst 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 rst byte of the following instruction.
