7.4.1 System Management Bus (SMBus) Mode

The SMBus interface can also be used to control the device. If MODE_SEL = Low (1 kΩ to VSS), Pins 13 and 29 are configured as SDA and SCL. Pins 11 and 28 are address straps ADDR0 and ADDR1 during power up. The maximum operating speed supported on the SMBUS pins is 400 kHz.

(1) The 8-bit write command consists of the 7-bit slave address (Bits 7:1) with 0 appended to the LSB to indicate an SMBus write. For example, if the 7-bit slave address is 0x2D (010 1101'b), the 8-bit write command is 0x5A (0101 1010'b).
