## Random-access memory
From a storage point of view, the cpu memory spaces are organized as identical arrays of 16-bit words. The cpu has access to its full address space: 65,6536 (0x10000) words of memory (total 128KB). By default, the stack base is at address 0xFFFF and grows towards lower addresses.

| **SF** (Sign flag) | Indicates that the most significant (leftmost) bit of the result of an operation is set |
| **OF** (Overflow flag) | Relevent for *signed* operations. Indicates that the sign of the result of an signed operation is wrong (See exemples below) |

| **BF** (Break flag) | Tells the CPU to stop the execution. This flag is set with the **BRK** instruction. |
