• Effective JUMP Address[15:0] = NextPC + Sign-Extend(#offset6);
+/- 32 instructions
The function NextPC indicates the instruction that would be fetched next by the program
counter. Instructions using this addressing are JL, JC and JC.I.
For absolute addressing, the actual address in CMEM where program flow is to resume
is either an immediate value #imm16 in the CMEM location immediately following the
jump instruction, or it is contained in the lower 16 bits of a register. If the value is greater
than the PC size implemented, an error condition has occurred.
• Effective JUMP Address[15:0] = #imm16
• Effective JUMP Address[15:0] = <R[a]>
Instructions using these addressing modes are JC.A (immediate absolute address) and
JC.IA (indirect absolute address).
