TR trigger

		`\| Vectorized \| C \|`
`in the palette`	`on the schematic`	`\| Vectorized \| C \|`

Implements a reset-priority TR 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 priority-reset RS-trigger:

where y(t) is the output signal of the block, x_S(t), x_R(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

none
