Implement extra functions with the NCP5608 LED driver

With more than 500mA output current capability, the NCP5608 is capable to drive the high power LED used in the portable photo flash system. Although the embedded I2C makes programming the chip very easy, it turns out that the flash can be trigged by the camera with no access to the I2C protocol. In this case, an extra function is necessary to support this specific pulse mode.

This Application Note depicts a simple way to implement such a need without sacrificing extra GPIO at MCU level.
