Source form
Everything in the source forms columns, except expressions in italic characters, is literal information
which 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
66
opr16a — Any label or expression that evaluates to a 14-bit value. On the RS08 core, the
opr4a — Any label or expression that evaluates to a Tiny address (4-bit value). The
opr5a — Any label or expression that evaluates to a Short address (5-bit value). The
opr8a — Any label or expression that evaluates to an 8-bit value. The instruction treats
opr8i — Any label or expression that evaluates to an 8-bit immediate value.

instruction treats this 4-bit value as the low order four bits of an address in the
16-Kbyte address space ($0000–$000F). This 4-bit value is embedded in the
low order four bits in the opcode.
instruction treats this 5-bit value as the low order five bits of an address in the
16-Kbyte address space ($0000–$001F). This 5-bit value is embedded in the
low order 5 bits in the opcode.
this 8-bit value as the low order eight bits of an address in the 16-Kbyte
address space ($0000–$00FF).
upper two bits are always 0s. The instruction treats this value as an address in
the 16-Kbyte address space.
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.
