When the execution condition for JMP0(515) is OFF, all instructions
from JMP0(515) to the next JME0(516) in the program are processed
as NOP(000). Use JMP0(515) and JME0(516) in pairs. There is no
limit on the number of pairs that can be used in the program.

N: Jump number
The operation of CJP(510) is the basically the opposite of JMP(004).
When the execution condition for CJP(510) is ON, program execution
j
umps directly to the first JME(005) in the program with the same jump
number. CJP(510) and JME(005) are used in pairs.
