Expand description
Pin Interrupt (PINT) driver for the LPC55S6x family.
The PINT block provides edge‑sensitive and pattern‑match interrupt generation from GPIO pins. It works in conjunction with the IOCON and INPUTMUX modules to route physical pins into the PINT channels.
Features supported:
- Up to 8 independent pin interrupt channels
- Configurable rising, falling, or both‑edge detection
- Pattern match engine for complex multi‑pin conditions
- Interrupt status and enable/disable control per channel
- Integration with NVIC for interrupt delivery to the Cortex‑M33 core
