Central Processor Unit (CPU)
Source form
Everything in the source forms columns, except expressions in italic characters, is literal information that
must appear in the assembly source file exactly as shown. The initial 3- to 5-letter mnemonic is always a
literal expression. All commas, pound signs (#), parentheses, and plus signs (+) are literal characters.
n — Any label or expression that evaluates to a single integer in the range 0–7
opr8i — Any label or expression that evaluates to an 8-bit immediate value
opr16i — Any label or expression that evaluates to a 16-bit immediate value
opr8a — Any label or expression that evaluates to an 8-bit value. The instruction treats
this 8-bit value as the low order 8 bits of an address in the direct page of the
64-Kbyte address space ($00xx).
opr16a — Any label or expression that evaluates to a 16-bit value. The instruction treats
this value as an address in the 64-Kbyte address space.
oprx8 — Any label or expression that evaluates to an unsigned 8-bit value, used for
indexed addressing
oprx16 — Any label or expression that evaluates to a 16-bit value. Because the HCS08
has a 16-bit address bus, this can be either a signed or an unsigned value.
rel — Any label or expression that refers to an address that is within –128 to +127
locations from the next address after the last byte of object code for the current
instruction. The assembler will calculate the 8-bit signed offset and include it in
the object code for this instruction.
Address modes
INH = Inherent (no operands)
IMM = 8-bit or 16-bit immediate
DIR = 8-bit direct
EXT = 16-bit extended
IX = 16-bit indexed no offset
IX+ = 16-bit indexed no offset, post increment (CBEQ and MOV only)
IX1 = 16-bit indexed with 8-bit offset from H:X
IX1+ = 16-bit indexed with 8-bit offset, post increment
(CBEQ only)
IX2 = 16-bit indexed with 16-bit offset from H:X
REL = 8-bit relative offset
SP1 = Stack pointer with 8-bit offset
SP2 = Stack pointer with 16-bit offset
