Detailed Description

One pin under software edge detection.

The stored level is what makes the detector an edge detector rather than a level poller: it is seeded at registration from a live read, so the first sampling pass compares against reality and cannot invent an edge that never happened.

Invariant

used is true exactly when handler is non-null.

sense is 0..3, using the ra8_icu_irqmd_t encoding.

last_level is 0 or 1.

Example:

ra8_esp_hosted_gpio_edge_row_t row = {};
