The OS reception area clear request (RYn6) is turned ON to abort the data in the R2
OS reception area.
When OS reception area clear is completed, the R2 turns the OS reception area clear
complete (RXn6) ON, so the OS reception area clear request (RYn6) will turn OFF.

This signal indicates the control signal status (CS, DR, CD signal) during RS-232-C
communication with an ON or OFF state.
This signal indicates the status of the R2 general-purpose external input (XC, XD)
status with an ON or OFF state.
RXnC: Corresponds to XC
When writing in the initialization data before executing initialization, the initial data read
request (RY(N+1)9) turns ON, and the initialization data is written to the master station.
At this time, remote station ready (RX(n+1)B) turns OFF.
When the writing is completed, initial data read complete (RX(n+1)9) turns ON, and
the initial data read request (RY(n+1)9) turns OFF.
When these turn OFF, initial data read complete (RX(n+1)9) turns OFF, and remote
station ready (RX(n+1)B) turns ON.
