| Overview | |
| -------- | |
| Configures port pins for switches and calls user defined function on switch press. Switch presses can be detected using | |
| IRQ interrupts or by polling. The benefit of using interrupts is that no extra processing is used for polling and the | |
| use of a system timer tick is not a requirement. The downside of using interrupts is that callback functions are called | |
| from within an interrupt so if your ISR is long then it can degrade the real-time response of your system. The benefit | |
| of polling is that functions are called at the application level and debouncing is supported. The downside to polling is | |
| that your system must call the R_SWITCHES_Update() on a regular basis which requires extra processing. | |
| Features | |

| * Can be configured to be interrupt or poll driven. | |
