Bits
Name
Type
Function
[63:32] SYS_ENM_H_CL0
RO
Most significant 32 bits of a 64
‑
bit representation of the
accumulated energy consumption of the N1 SoC cluster 0:
•
The memory address offset of these bits is
0x010C
.
•
Accumulated energy =
(SYS_ENM_H_CL0:SYS_ENM_L_CL0)/6174020000 joules.
•
The
CB_nRST
reset signal resets the register to zero. The
register then updates every 100µs after the reset.
[31:0]
SYS_ENM_L_CL0
RO
Least significant 32 bits of a 64
‑
bit representation of the
accumulated energy consumption of the N1 SoC cluster 0:
•
The memory address offset of these bits is
0x0108
.
•
Accumulated energy =
(SYS_ENM_H_CL0:SYS_ENM_L_CL0)/6174020000 joules.
•
The
CB_nRST
reset signal resets the register to zero. The
register then updates every 100µs after the reset.
