4.3.23. SYS_VOLTAGE[7:0]

These registers are used to read voltage and current measurements for the attached Core Tiles.

Note

The function of these registers might be different for the combination of boards that you are using. Read the application note for your system for any changes to this register area.

Table 4.26 lists the bit mapping for reading the different voltage measurements:
