8.2.4 Mezzanine TSI Telecom clocks
8.2.5 MMC I2C Interface (Slave)
The MMC I2C Interface is used to access ARTM Base FPGA registers thru Glue Logic FPGA and
to access one of the selected SFP I2C devices. The I2C slave address for ARTM Base FPGA
registers is 0xFE. Other I2C accesses are forwarded to the selected. SFP I2C device.
8.2.6 I2C Interfaces to Sonet SFP and 10GE SFP+
The I2C Interfaces are connected to the corresponding SFP cages. Thru the ARTM Base Glue
Logic FPGA, one selected interface can be accessed with the MMC I2C interface.
