DESCRIPTION
Data addressing modes
Rr
working register R0-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
11-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.
