Implements a set-priority TS trigger model with the countable input. If at least one of the inputs R or S is supplied with a logical unit, then the trigger works as a set-priority RS-trigger:
where y(t) is the output signal of the block, xS(t), xR(t) is the first and third input signals of the block (from English: Set and Reset).
where y(t) is the output signal of the block, xS(t), xR(t) is the first and third input signals of the block (from English: Set and Reset).
If a logic zero is applied to both inputs R and S, then the trigger acts as a counting trigger that changes its dependency state based on the type of counting input:
- by the front – when changing the value at the synchronizing input from 0 to 1;
- by the drop – when changing the value at the synchronizing input from 1 to 0;
- by the front and drop – in case of any change in the value at the synchronizing input;
- by level – when a logical unit is supplied to the synchronizing input (the state of the trigger will change at each step of the interval).
Input ports
- S – the input port for setting the trigger;
- T – countable input port of the trigger;
- R – the input port for resetting the trigger.
Output ports
- out – trigger output port;
- Yinv – the inverse output port (optionally added in the block properties).
Properties
- Initial conditions – initial values of the output logic signal;
- Counting input type – counting input triggering condition;
- Add inverse output – indicates the presence of an inverse output.
Parameters
