Timer Interrupt Block¶
How this block appears in a Simulink model?¶
What can be configured?¶
| Configuration Parameter | Selectable Option/Value | Description |
|---|---|---|
| Timer group | 0--1 | Select timer group |
| Module | 0--1 | Select timer module |
| Advanced settings | Check--Uncheck | |
| Timer pre-scaler | 2--4--8--16--32--64--128 | How quickly the timer’s counter is “ticking”. This depends on the setting of divider, that will be used as divisor of the incoming 80 MHz APB_CLK clock. |
| Count direction | Count up--Count down | Sets if the counter should be incrementing or decrementing. |
| Alarm | Enable--Disable | Enable/Disable the alarm. |
| Alarm mode | With reload--Without reload | Set if the initial counter value should be reloaded on the timer’s alarm. |
| Interrupt interval (sec) | Select the interrupt interval. |
When to use this block?¶
This block can be used to set up an Interrupt Service Routine (ISR) that could be triggered by a built in TIMER module.
How does this block work?¶
Depending on the input trigger configuration, when the specified trigger conditions are met the block will output a logic ‘true’ signal that could activate a function call subsystem in Simulink.
