2. CPU

2.1. CPU Core

CPU Core (H08A) adopts Harvard architecture concept in order to enhance execution

efficiency. Separate program memory and data memory incorporated in program memory

address increases user convenience of program writing.

CPU features include：

Isolated design frame of program memory and data memory upgrades instruction

execution speed and CPU efficiency.

Maximum address ability: 8KW for program memory and 256KB for data memory.

At most 67 instructions including 16-bit look-up-table, 8x8 hardware multiplier and

program memory block switch and stack control.

One instruction accomplished data movement from register A to register B without

changing work register data.

One instruction accomplished utmost 16-bit FSR register data movement and

address 8KW program memory look-up-table instruction.

Data memory operation includes Program Counter (PC), Status Register (Status)

and Stack Register (Stack) data movement.

Processor core is H08A core.
