Data types and memory handling
MSP430 architecture processors use a single address space to map data and code. The registers and memory are 16 bits wide, and the CPU can only read and write 16 bit data at even addresses. If you attempt to read or write a 16 bit value at an odd address, the CPU behaves as if the LSB is not set. The processor has no exception handling. The MSP430 can read and write 8 bit data at any address.
The C compiler supports the following basic data types
•char - 1 byte (8 bits)
•int - 2 bytes (16 bits)
•long - 4 bytes (32 bits)
•long long - 8 bytes (64 bits)
•float - 4 bytes
