variable n represents a decimal number; aa represents a hexadecimal address; and LABEL
represents a label defined elsewhere in the assembly source.
In reference notation, only lowercase is used to distinguish 4-bit addressed working
registers (r1, r2) from 8-bit addressed registers (R1, R2). The numerals 1 and 2,
respectively, indicate whether the register is used for destination or source addressing.

cc represents a condition code mnemonic. See
Immediate Data
IM represents an Immediate Data value, prefixed by # in assembly language
where n = 0 to 255.
The immediate value follows the instruction opcode in Program Memory.
Working Register
r1 or r2 represents the name, R
The equivalent 12-bit address is {RP[3:0], RP[7:4], n }.
Working Register Pair
rr1 or rr2 represents th e name, R
n = 0, 2, 4,..., 14. The equivalent 12-bit address is {RP[3:0], RP[7:4], n }.
Register
R1 or R2 represents an 8-bit register address. For addresses 00h–DFh or
F0h–FFh , the equivalent 12-bit address is {RP[3:0], %
E0h–EFh (escaped mode), the equivalent 12-bit address is
{RP[3:0], RP[7:4], %
