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.
