Note1: Comply to 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 RESET, IDLE, OVUVFLT, and
THERMAL states to clear any transactions that may have been occurring when entering the above states.
Note3: This is an I2C system specification only. Rise and fall time of SCL & SDA not controlled by the device.
Note4: Device Address is 7’h5A
