Note 11-7:
This test point is used for DCXO calibration Note 11-8:
without battery.
VRTC: 32.768 KHz crystal is not existed
GND: 32.768 KHz crystal is existed
Total capacitor value at VBAT must larger than 28.4uF for DL

VSWXM: Switch off power supply in suspend mode
VIO18: 32.768KHz crystal existed
VA18: 32.768KHz crystal less
No burning eFUSE case: Pin FSOURCE_D is tied to GND .
Pin FSOURCE_D connected to VEFUSE
Burning eFUSE case is needed:
to C1109 GND side by point directly which without any branch.
Active eMMC should unmount R1113 and mount J1111.
