Understanding the register set is crucial for writing efficient assembly programs: AXcap A cap X (Accumulator), BXcap B cap X CXcap C cap X (Count), and DXcap D cap X Pointer and Index Registers: SPcap S cap P (Stack Pointer), BPcap B cap P (Base Pointer), SIcap S cap I (Source Index), and DIcap D cap I (Destination Index). Segment Registers: CScap C cap S (Code Segment), DScap D cap S (Data Segment), SScap S cap S (Stack Segment), and EScap E cap S (Extra Segment).
Memory is divided into segments of 64 KB each. The is calculated using the formula:
