4.13 Other interface
4.13.1 Camera flash Signal
These camera flash signal provide flash and torch mode enable. The FLASH_NOW trigger the
camera flash into torch mode. The FLASH_EN enable the camera flash to flash mode.
4.13.2 PM_VIB_DRV_N Signal
The PM_VIB_DRV_N is used to control vibration intensity. The vibration driver is a
programmable voltage output that is referenced to VDD; when off, its output voltage is VDD. The
motor is connected between VDD and the PM_VIB_DRV_N pin.

4.13.3 VCOIN Signal
VCOIN requires either a lithium manganese dioxide rechargeable coin cell or a keep-alive
capacitor, so that the appropriate oscillator and real-time clock circuits continue to run when the
phone is off.
