Description
Register Pair (8-bit Address)
RR1 or RR2 represents the 8-bit address of a register pair. For addresses
00h–DFh or F0h–FFh , the equivalent 12-bit address is {RP[3:0], %
For addresses E0h–EFh (escaped mode), the equivalent 12-bit address is
{RP[3:0], RP[7:4], %
Indirect Working Register
Ir1 or Ir2 represents the name a working register, R n, where n = 0, 1, 2,..., 15.
@ indicates Indirect Working register addressing using an 8-bit effective
address contained in the specified working register. The accessed register’s
equivalent 12-bit address is {RP[3:0], 8-bit effective address }.
Indirect Working Register Pair
Irr1 or Irr2 represents the name of a working register pair, RRn, where n = 0, 2,
4,..., 14.
@ indicates Indirect Working register addressing using an effective address in
the specified working register pair. Depending on th e instruction, the effective
address is in the register file (12-bit address) or Program/Constant Memory
(16-bit address).
Indirect Register
IR1 or IR2 represents the 8-bit address of a register.
@ indicates Indirect register addressing using an 8-bit effective address
contained in the specified r egister. The accessed register’s equivalent 12-bit
address is {RP[3:0], 8-bit effective address }.
Indirect Register Pair
IRR1 represents the 8-bit address of a register.
@ indicates Indirect register addressing with a 16-bit effective address (in
Program Memory) contained in the specified register pair.
Indexed (X) Addressing
X represents the 8-bit base address to which the offset is added.
r1 or r2 represents the name, R
signed offset. The 8-bit effective address is the sum of X and the contents of
working register R
