Purpose
Contains a 12
‑
bit representation of the instantaneous current consumption of N1 cluster 0.
Usage constraints
This register is read
‑
only. You must use one of the cluster 1 cores to read this register.
Configurations
Available in all N1 board configurations.
Memory offset and full register reset value
See
4.7.1 APB energy meter registers summary
Note
The value measured by this register is provisional and subject to characterization on the RevB boards.
The following table shows the bit assignments.

bit representation of the instantaneous current consumption of
N1 cluster 0:
•
Full scale measurement, 4096, represents 10A. Full scale is
0xFFF
.
•
Measured current = (SY1)/381 amperes.
•
The
CB_nRST
reset signal resets the register to zero. The
register then updates every 100µs after the reset.
