BCC (Board Configuration Controller) FPGA
7.5
The Board Configuration FPGA is factory configured, and handles the basic board setup and User FPGA
(Kintex-7) Configuration.
Changing or erasing the BCF (Board Configuration Firmware) content leads to an inoperable
TPCE636 FPGA configuration.
7.5.1 I2C Interface to BCC Register
The TPCE636 BCC provides an I2C Interface to the User FPGA (Kintex-7). Via this I2C Interface the
TPCE636 Serial Number Register from the BCC Local Configuration Register Space could be read.
For the User FPGA (Kintex-7) an I2C Master interface is required to use this interface. For this purpose the
BCC provides an I2C slave interface.
