Machine coding notation
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.
Address modes

opr16a — Any label or expression that evaluates to a 16-bit value. The instruction treats this
oprx16 — Any label or expression that evaluates to a 16-bit value. Because the HCS08 has a
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

Low-order 8 bits of a direct address 0x0000–0x00FF (high byte assumed to be 0x00)
Upper 8 bits of 16-bit offset
Lower 8 bits of 16-bit offset or 8-bit offset
One byte of immediate data
High-order byte of a 16-bit immediate data value
Low-order byte of a 16-bit immediate data value
High-order byte of 16-bit extended address
Low-order byte of 16-bit extended address
Relative offset
value as the low order 8 bits of an address in the direct page of the 64-Kbyte address
space (0x00xx).

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.
