4.1.4. Initialization /Internal bits backup

Value n to choose
n = 0 (default value)
n = 1...99
n = 100...229
n = 230...254
n < 0, n > 254
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.
4.1.5. Initialization / Internal words backup
Value n to choose
n = 0 (default value)
n = 1...99
