201811011I : PCA85233 Datasheet Device Initialization & Setup

Added sections 7.4.1 "Device Initialization" and 7.4.2 "Device Setup" to the PCA85233 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." Note: CIN #201811011I will be added to the "Revision History" section of the new PCA85233_5_20181108 DS uploaded in the "Files" section once the CIN is approved & distributed.
