D If the TMR SEL pin is left floating (3 HR time), a 10-pF capacitor should be installed between TMR SEL and CR.
D If a micro process is monitoring the STAT pins, it may be necessary to add some hysteresis into the feedback
to prevent the STAT pins from cycling while crossing the taper detect threshold (usually less than one half
second). See SLUU083 EVM or SLUU113 EVM for additional resistors used for the STAT pins.
