n = 230...254
n < 0, n > 255
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 diagnostic tasks.
The bit M 255,15 cannot be saved and is reset to 0 each time the program is started. It is
therefore suitable for recognizing the first program cycle.
Example: KW 00,01 = 20
Initialized bits: M 020,00...M 099,15
M 230,00...M 255,15
Backed up bits: M 000,00...M 019,15
