Detailed Description

Register-start-mode configuration block.

Filled by the caller and passed to ra8_wdt_init. Maps 1:1 onto the bit-fields of WDTCR + WDTRCR + WDTCSTPR.

 const ra8_wdt_cfg_t cfg = {
.timeout = k_ra8_wdt_timeout_4096,
.clock_div = k_ra8_wdt_clkdiv_128,
.window_start = k_ra8_wdt_window_start_100,
.window_end = k_ra8_wdt_window_end_0,
.on_expiry = k_ra8_wdt_on_expiry_reset,
.stop_in_sleep = k_ra8_wdt_sleep_stop_count,
 };
 (void)ra8_wdt_init(&cfg);

Invariant: window_end < window_start (silicon forces end=0% otherwise, per HUM Ch 27.2.2 p 1259).
