SLOS825E December 2012 – April 2018 DRV2605
The STANDBY bit in register 0x01 forces the device in an out of the standby state. The STANDBY bit is asserted by default. When the STANDBY bit is asserted, the DRV2605 device goes into a low-power state. In the standby state the device retains register values and the ability to have I2C communication. The properties of the standby state also feature a fast turn, wake up, and play, on-time. Asserting the STANDBY bit has an immediate effect. For example, if a waveform is played, it immediately stops when the STANDBY bit is asserted.
Clear the STANDBY bit to exit the standby state (and go to the ready state).
