Comments:
 The bits M 255.00 to M 255.03 are oscillator variables which always start at 0.
 The bits M 255.10 to M 255.14 are reserved for the diagnosis.
 The M 255.15 bit cannot be backed up and is always reset to 0 at the launch of any
program. Consequently, it may be used to detect the first program cycle.
