12-CHANNEL PoE MANAGER
I²C Interface
A standard I²C interface is used to communicate between the PD64012 and the host controller.
The PD64012’s I²C interface is designed to support the following features:
♦ SLAVE mode only
♦ Normal-mode and Fast-mode data rate (0 to 400 kb/s)
♦ 7-bit addressing - the 7-bit addressing (128 addresses) uses the following address code:
• First MSB = “0” (forced by internal logic)
• 4 MSB address bits are set via the I2C_INI pin, according to the following table
• “mm” bits are set through the ASIC_INI pin (Enhanced mode = “00”; Automatic mode Master
=”00”; Automatic mode Slave = “01”, “10”, “11”)
• “xxx” - 3 LSB are ignored.
