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
used.
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)
at little/big endian.
4. Make sure that the ADC registers, RTC registers and UART registers be read/written by the specified access
unit and the specified address. Moreover, one must carefully consider which endian mode is used.
5. W : 32-bit register, which must be accessed by LDR/STR or int type pointer(int *).
HW : 16-bit register, which must be accessed by LDRH/STRH or short int type pointer(short int *).
B : 8-bit register, which must be accessed by LDRB/STRB or char type pointer(char int *).
