2.1.2
In comparison to the H8/300 CPU, the H8/300H has the following enhancements.
Rev. 3.00 Mar 21, 2006 page 20 of 814
REJ09B0302-0300
Two CPU operating modes
Low-power mode
Transition to power-down state by SLEEP instruction
More general registers
Eight 16-bit registers have been added.
Expanded address space
Enhanced addressing
The addressing modes have been enhanced to make effective use of the 16-Mbyte address
space.
Enhanced instructions
16
32 ÷ 16-bit register-register divide:
Normal mode (not available in the H8/3052BF)
Advanced mode
Advanced mode supports a maximum 16-Mbyte address space.
Normal mode supports the same 64-kbyte address space as the H8/300 CPU.
(Normal mode is not available in the H8/3052BF.)
Data transfer, arithmetic, and logic instructions can operate on 32-bit data.
Signed multiply/divide instructions and other instructions have been added.
Differences from H8/300 CPU
16-bit register-register multiply:
0.88 µs
