(1) Pulse widths configured for less than 10ms (K×R×C < 10µs) can fail to properly trigger the state machine resulting in very short output pulses (two < 10µs).
(2) Pulse widths configured for more than 2253s (K×R×C > 2.2s) can vary significantly due to exceeding the digital timing circuitry capabilities.
