JME0 516 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.

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

The operation of CJPN(511) is almost identical to
JMP(004).
When the execution condition for CJP(004) is OFF,
program execution jumps directly to the first
JME(005) in the program with the same jump
number. CJPN(511) and JME(005) are used in
pairs.
