2.4.1. Information transmitted by Daughterboard Configuration Controller to the motherboard

The Daughterboard Configuration Controller transmits voltage measurements, information about the daughterboard oscillators, temperature measurements of the FPGA and information about the SCC registers supported in the FPGA design.

Table 2.3 shows the device numbers for the voltage supplies.
