IMPORTANT NOTES ABOUT S3C24A0A SPECIAL REGISTERS
1. The special registers have to be accessed by the recommended access unit.
2. All registers except ADC registers, RTC registers and UART registers must be read/written in word unit (32bit)
at little/big endian.
3. It is very important 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.
4. 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 *).
