SYS_I_PCIE
RO
12
‑
bit representation of the instantaneous current consumption of
the PCIe cluster:
•
Full scale measurement, 4096, represents 10A. Full scale is
0xFFF
.
•
Measured current = (SYS1)/381 amperes.
•
The
CB_nRST
reset signal resets the register to zero. The
register then updates every 100µs after the reset.
4.7.5
SYS_I_CL1 Register
The SYS_I_CL1 Register characteristics are:
Purpose
Contains a 12
‑
bit representation of the instantaneous current consumption of N1 cluster 1.
Usage constraints
This register is read-only. You must use one of the cluster 0 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.

SYS_V_SYS Register
The SYS_V_SYS Register characteristics are:
Purpose
Contains a 12
‑
bit representation of the instantaneous supply voltage of the parts of the N1 SoC,
outside the clusters, that operate from the VSYS power supply.
Usage constraints
This register is read-only.
