RESETN J8 N13 101 48
[5]
External reset input: A LOW on this pin resets the device,
causing I/O ports and peripherals to take on their default
states, and the boot code to execute. Wakes up the part
from deep power-down mode.

- - Ground.
VDDA J4 N6 64 32 - - Analog supply voltage.
VREFN - N4 59 - - - ADC negative reference voltage. On TFBGA100 and
LQFP100 packages, the ADC negative reference voltage is
internally tied to the VSSA pin.
VREFP K4 P6 63 31 - - ADC positive reference voltage.
VSSA H4 L5 60 30 - - Analog ground. On TFBGA100 and LQFP100 packages,
the ADC negative reference voltage is internally tied to the
VSSA pin.

- - Main oscillator output.
VBAT K9 N11 94 45 - - Battery supply voltage. If no battery is used, tie VBAT to
VDD or to ground.
RTCXIN J9 L12 105 51 - - RTC oscillator input.
RTCXOUT H9 K11 106 52 - - RTC oscillator output.
