Instruction Set
JC
Jump if carry set
JHS
Jump if higher or same
Syntax
JC
JHS
If C = 1: PC + 2 × offset −> PC
Operation
If C = 0: execute following instruction
Description
The status register carry bit (C) is tested. If it is set, the 10-bit signed offset
contained in the instruction LSBs is added to the program counter. If C is reset,
the next instruction following the jump is executed. JC (jump if carry/higher or
same) is used for the comparison of unsigned numbers (0 to 65536).
Status Bits
Status bits are not affected.
Example
The P1IN.1 signal is used to define or control the program flow.

Example
R5 is compared to 15. If the content is higher or the same, branch to LABEL.
