Miscellaneous Functions
The drivers and comparators for a USB On-the-Go and a CEA-936-A compatible USB carkit including
audio routing, as well as RS232 interfaces are provided. Special precautions are taken to allow for specific
booting and accessory detection modes.
Current sources are provided to drive tricolored funlights and signaling LEDs. The funlights have
preprogrammed lighting patterns. The wide programmability of the tricolored LED drivers allows for
applications such as audio modulation. Three backlight drivers with auto dimming are included as well for
keypad and dual display backlighting.
A dedicated interface in combination with the A to D converter allow for precise resistive touchscreen
reading. Pen touch wake up is included.
