In the Speedy Lock mode, the OUT0 and OUT1 pins can be utilized as synchronous switches between active low
and a tri-state. The Speedy Lock mode activates the OUT0 and OUT1 pins to be connected to GROUND with a
low impedance(< 150
) while a high charge pump gain(≥ 8X) is selected and otherwise to a tri-state. For using a
programmable CMOS output, the CMOS output bit(W2[21]= LOW) should be activated and then the desired logic
level should be programmed with the control bits W2[19] for OUT0 and W2[20] for OUT1.
