At continuous execution of a different start channel
The activate request of the next start channel is output regardless with the
state of the data protection.
When the final start channel processing to be
scanned is completed, the scanning conversion is
dormant.

[Channel composition information]
Start channel N, N+1, and N+2: It is a stop scanning conversion mode, and is conversion frequency specification scanning conversion
execution permission, and it are the repetition mode and the security function, and is a software start (The N?N+2 channel is converted the
scanning), and is a continuous conversion frequency: Start channel N+2 = twice start channel N+1 = once start channel N= twice
