Extended Instruction Set - Holtek HT67F2350 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 sector except sector 0, the extended
instruction can be used to directly access the data memory instead of using the indirect addressing
access. This can not only reduce the use of Flash memory space but also improve the CPU execution
efficiency.
