201810014I : PCA85262 Datasheet Device Initialization & Setup

Added sections 7.4.1 "Device Initialization" and 7.4.2 "Device Setup" to the PCA85262 DS as follows: 7.41 Device InitializationAt power-on the status of the I2C-bus communication interface is undefined since this device doesn¿t have POR which was removed to improve the ESD performance. A START and STOP condition with dummy byte in-between must be sent after every power reset to set up the I2C-bus communication interface.Also added the following note to the 3rd bullet of section 7.4.1 "Device Initialization" outline: "Note this is not the device address but just a dummy byte of all zeros."7.42 Device SetupAt power-on the status of the display and configuration registers are undefined and need to be set up to properly display information on the LCD display. After the I2C-bus interface is initialized as discussed in 7.41 set up the device using these register settingsAlso added the following note to the last bullet of section 7.4.2 "Device Setup" outline: "or left off (blank) with bit E = 0."
