Note 2

tied to ground all outputs low and tied to ground

Note 3

When forcing HALT current is only needed for a short time (approx 200 ns) to flip the HALT flip-flop

Note 4

This parameter is only sampled and not 100% tested Variation due to the device included

Note 5

Voltage change must be less than 05 volts ina1ms period
