‑
bit representation of the instantaneous supply voltage of the
parts of the N1 SoC, outside the clusters, that operate from the
VSYS power supply:
•
Full scale measurement, 4096, represents 2V5. Full scale is
0xFFF
.
•
Measured voltage = (SY1)/1622 volts.
•
The
CB_nRST
reset signal resets the register to zero. The
register then updates every 100µs after the reset.
