The "bit addressable memory space" refers to a memory area where individual bits can be accessed and manipulated. In the context of an ALU (Arithmetic Logic Unit), the carry flag is a single bit that is used to indicate whether an arithmetic operation resulted in a carry out of the most significant bit.
When writing bits to the ALU carry flag, the bit addressable memory space is accessed and the desired bit is set to 1 or 0 depending on the value being written. This is typically done using bitwise operators in the programming language being used. For example, in C, the bitwise OR operator (|) can be used to set a bit to 1, while the bitwise AND operator (&) can be used to set a bit to 0.
It's important to note that the specifics of how this is implemented may vary depending on the particular ALU architecture and programming language being used.
