Detailed Description

One row of the pin-to-ICU-channel routing table.

A flat pair rather than a sparse array indexed by pin: the table holds a handful of rows, and a linear scan over a compile-time-sized array cannot be indexed out of range, which keeps the lookup inside NASA Power of 10 Rule 2 without a bounds check on caller-supplied data.

Invariant

pin is a packed RA8_PIN(port, pin) code.

irq is 0..15 or k_ra8_esp_hosted_irq_none.

Example:

const ra8_esp_hosted_irq_route_row_t row = { .pin = 0x0006U, .irq = 11U };
