I2C Timeout Function
tout
Total time required for I2C communication to
cause I2C state machine to reset
100
ms
Note1: Comply with I2C timings for 1MHz operation - “Fast Mode Plus”.
Note2: No internal timeout for I2C operations, however, I2C communication state machine will be reset when entering UV/POR State.
Note3: This is an I2C system specification only. Rise and fall time of SCL & SDA not controlled by the IC.
Note4: IC Address is factory configurable to 7’h24, 7’h66.
