ENSEL_4V: Enable selector for four values
Block ENSEL_4V [FB456] as a central block allows for selective interconnection of 8 multistate values (1of 8) based on particular priority. The multiple inputs have two multistate values and two real values available.
Functionality
To interconnect multiple multistate and real values based on a specified priority, the block ENSEL_4V forwards the values of the multiple inputs [Val1xx..Val8xx] to outputs [Outxx].
The following conditions apply:
- A multistate signal is available at the impacted value input (e.g. Off-Stage15).
- A real value is pending at the corresponding value input.
- The impacted value inputs [Val1xx..Val8xx] = Off-Stage15 or real value is enabled by the corresponding enable pin [En1..8] = 1 (Yes).
- There is no higher-value input [Val1xx...Val8xx] is pending at outputs [Outxx].
- If multiple value inputs [Val1xx..Val8xx] are enabled [En1..8], the pin with the highest priority (lowest number) is switched to output [Outxx].
- Output [InNr], contains an integer number according to the number of the input [Val1xx..Val8xx] routed to output [Outxx].
- If all enable pins [En1..8] = 0 (No), output [Outxx] is set to the default value [Defxx] and output [Enable] = 0 (No).
- If the outputs [Outxx] represent a valid value, output [Enable] = 1 (Yes).
