28 GND - - - Ground
29 PON I - I (270k
fixed
pull-
down)
Power on, Switches on the device if Voltage > 1.5 V.
May be directly connected to VBAT, also with Li-Ion batteries.
After startup the software takes over then PON pin to keep the
device on after which the PON pin may be released.
30 ULP_XTAL I - I 32.768 kHz XTAL clock input. Connect to GND if not used. (Note 3)
31 ULP_PORT I - I Ultra Low Power Port Pin. Connect to GND if not used. (Note 3)

pull-up)
Active low Reset input with Schmitt-trigger input, open-drain output
and pull up resistor to internal VDD. Input may not exceed 2.0 V. An
internal capacitor of 47 nF is mounted on this pin.
53 JTAG IO 8 I-PU JTAG-SDI+; one wire Debug interface with open-drain.
Requires external 1 k pull-up to VDD.
