+Let's see if Pirelli's PCB layout implements the "special" GND for the 32 kHz
+oscillator like TI's schematics and app notes indicate.
+
+VSSO ball (A14): no trace on L1, so must be a micro-via right under the ball
+itself. L1 coord (3640,1049). GND side of the cap for V-RTC power balls:
+micro-vias at (3435,970) and (3458,980).
