Low Addresses
An example is shown below in which the output pattern to the real-time output port and the output interval are directly
controlled.
Update data is transferred from the two data storage areas set in the 1 M-byte space beforehand to the real-time
output function buffer register (P0L) and the compare register (CR10).
