Des cription
Constant voltage reference.
External 2 kohm 1% resistor connection to VSS is
required for this pin.
1.2V Regulator Disable.
Tie to VDDO to disable, Tie to VSS to enable.
2.5V Regulator Control.
This signal ties to the base of the BJT. If the 2.5V
regulator is not used it can be left floating.
De scr ip tio n
Test Pin.
These pins have 49.9 ohm internal termination.
They should be brought out to a via or pad to facili-
tate debug. If debug is not important and there are
board space constraints, this pin can be left float-
ing.
