Detailed Description

One pin served by a real ICU external-interrupt channel.

The trampoline installed with the HAL receives this row as its context, so it can reach the vendored callback without a search. The row also carries the channel number, which teardown needs and the vendored driver never learns.

Invariant: used is true exactly when handler is non-null.; irq_num is 0..15 while used is true.

Example:: ra8_esp_hosted_gpio_irq_row_t row = {};
