7. Functional Description
7.1 Internal Oscillator
The HX8340-B can oscillate an internal R-C oscillator for internal operation. Because the tolerance of internal oscillator frequency is ±5%, it can be adjusted for initial 2.52MHz internal clock generation. With other dividers setting, the 2.52MHz internal clock can be used to generate clock for other part of the chip using. In RGB interface mode (RCM[1:0] = ‘10’ or ‘11’), external DOTCLK will be replace the internal clock for other part of the chip using.
