Positive Capacitor connection.
This is the positive terminal of the charge pump. A capacitor, with a 2.2
µF recommended value, is required to connect between PCAP and
NCAP. If this pin is not used, it must be left unconnected/floating. In this
case, no capacitor is needed. Analog charge pump capacitors are not
needed if none of the analog SCB features are used, and none of the
SDDs are used.
Pass transistor base connection
This is the control signal of the voltage regulator. This pin should be
connected to the base of an external pass transistor used with the 1.5
V internal voltage regulator and can be floating if not used.
Pass transistor emitter connection.
This is the feedback input of the voltage regulator.
This pin should be connected to the emitter of an external pass
transistor used with the 1.5 V internal voltage regulator and can be
floating if not used.
Reset signal for the microcontroller subsystem.
Push-button is the connection for the external momentary switch used
to turn on the 1.5 V voltage regulator and can be floating if not used.
