PVT sensor registers
The Musca
‑
S1 test chip implements registers that monitor the
Process, Voltage, Temperature
(PVT)
sensor system.
This section contains the following subsection:
•
3.9.1 PVT sensor control registers summary
3.9.1
PVT sensor control registers summary
The PVT sensor control registers are mapped to both the Non
‑
secure and Secure Expansion 1 regions.
The base memory addresses of the PVT sensor control registers are:
•
0x4010_9000
in the Non
‑
secure region.
•
0x5010_9000
in the Secure region.
The following table shows the PVT sensor control registers in address offset order from the base memory
address. Undefined registers are reserved. Software must not attempt to access these registers.
