JC rel
Appendix A : Instruction Set (12/19)
Binary Code
Description
Carry Flag
Operation
L_C_SET:
Example
Cycles
Bytes
Branches if the carry flag is 1.
The branch destination is computed by adding
the signed relative-displacement in the
second byte of the instruction to the PC, after
incrementing the PC to the start of the next
instruction.
(PC) ← (PC) + 2
IF (C) = 1 THEN (PC) ← (PC) + rel
Not affected.

JMP addr
Binary Code
Description
Carry Flag
Operation
Example
Cycles
Bytes
Transfers program execution to the indicated
12-bit address.
The destination address is obtained by
concatenating the four low-order bits of the
opcode byte and the second byte of the
instruction.
(PC) ← addr
Not affected.
