Data cannot be saved and transferred at the same time. Attempting to do so
will result in a multiple start error (error code 8000). It is also not possible to
save data while pulses are being output. The following diagram is a timing
chart for saving data.

It is possible to use the CX-Position Support Software to read, write and save
data, and to monitor the operating status of the PCU.
CX-Position is software that can be used for setting all kinds of data used by a
PCU as well as for monitoring the operating status of the PCU.
Refer to the CX-Position Operation Manual (W433) for details on its operation.
While CX-Position is used to download data, or to save data to flash memory,
the Data Transferring Flag will be ON.
