The TRIGOVRFLW task sets the COUNTER value to 0xFFFFF0 to allow SW test of the overflow condition. OVRFLW occurs when COUNTER overflows from 0xFFFFFF to 0.

Important: The OVRFLW event is disabled by default.

Here we cover the pin assignments for each variant of the chip.

Maximum ratings are the extreme limits to which the chip can be exposed for a limited amount of time without permanently damaging it. Exposure to absolute maximum ratings for prolonged periods of time may affect the reliability of the device.
