Table 282: PRIO_L1_5 bits information
Bits Bits description
1...5 Sheddable load1 priority
6...10 Sheddable load2 priority
11...15 Sheddable load3 priority
16...20 Sheddable load4 priority
21...25 Sheddable load5 priority
Similarly, the priority for each sheddable load that is sheddable
load6...10 is represented by consecutive five bits of PRIO_L6_L10.
The output B_SET_CHANGE remains active for 500 ms if one or more basic settings
are changed. After 500 ms, the output B_SET_CHANGE is FALSE.
The group output BB consists of signals for ten sheddable loads which are provided to
the LSCACLS function.
