Power On

• Start: initial state the VCC/VDD, RES, SDA, SCL = 0

Power on response time needs less than 1000 ms when the IC is powered on into the active mode. The response time of system from standby mode to active mode needs less than 35 ms. The response time of system from sleep mode to active mode needs less than 1000 ms.

The RESET pin needs to draw low 5ms first then power on. The time of power on should be

as short as possible, can guarantee to finish in 1ms. Wait for 5ms after power on ready then the RESET pin draws high. After the RESET draws high 1000ms, I²C can start to operate for read or write.
