PRODUCT OVERVIEW
Cautions on S3C2410A Special Registers
1. In the little endian mode, L. endian address must be used. In the big endian mode, B. endian address must be
2. The special registers have to be accessed for each recommended access unit.
3. All registers except ADC registers, RTC registers and UART registers must be read/written in word unit (32-bit)
4. Make sure that the ADC registers, RTC registers and UART registers be read/written by the specified access
