Extended Inst - Holtek BS83B24C Manual

Extended Instruction Set
The extended instructions are used to support the full range address access for the data memory.
When the accessed data memory is located in any data memory sections except sector 0, the
extended instruction can be used to access the data memory instead of using the indirect addressing
access to improve the CPU firmware performance.
