9.8. Programming SMBus (or I2C) address

The DIO1413C and DIO1414C SMBus (or I2C) client address are determined by the pull-up resistor on the

______

THERM/ADDR pin as shown in the below table. The address decode is performed after power-up the device.

For the first 15 ms after power-up the device may not respond to SMBus (or I2C) communications.
