NWDT_TIME_LOWER_LIMIT

#define NWDT_TIME_LOWER_LIMIT   (1U)

Lower bound time.

Actual Lower Limit is ~100us so round up

Definition at line 35 of file cpu_wdt.h.

NWDT_TIME_UPPER_LIMIT

#define NWDT_TIME_UPPER_LIMIT

Value:

                                        (4U * US_PER_MS * 4096U * (1 << 6U) \
                                        / CLOCK_LSI)

Upper bound time.
