As the number of the numeral table is written, the PT status numeral setting
strobe flag is simultaneously set ON (1). After this is notified to the PC, this flag
reverts to OFF (0). Checking the status of this flag will provide a simple method
of checking if a number has been input from the NT11S.
Note that this function is not available with the character-string memory table.
