Section 2 CPU

Microcontrollers of the H8/36079 Group and H8/36077 Group have an H8/300H CPU with an

internal 32-bit architecture that provides upward compatibility with the H8/300CPU. Products of

the H8/36079 Group support an advanced mode with a 16-Mbyte address space while those of the

H8/36077 Group support a normal mode with a 64-Kbyte address space.

• Upward compatibility with H8/300 CPUs

 Can execute object programs for H8/300 CPUs

 Additional eight 16-bit extended registers

 32-bit transfer and arithmetic and logic instructions are added

 Signed multiply and divide instructions are added.

• General-register architecture

 Sixteen 16-bit general registers also usable as sixteen 8-bit registers and eight 16-bit

registers, or eight 32-bit registers

• Sixty-two basic instructions

 8/16/32-bit data transfer and arithmetic and logic instructions

 Multiply and divide instructions

 Powerful bit-manipulation instructions

• Eight addressing modes

 Register direct [Rn]

 Register indirect [@ERn]

 Register indirect with displacement [@(d:16,ERn) or @(d:24,ERn)]

 Register indirect with post-increment or pre-decrement [@ERn+ or @–ERn]

 Absolute address [@aa:8, @aa:16, @aa:24]

 Immediate [#xx:8, #xx:16, or #xx:32]

 Program-counter relative [@(d:8,PC) or @(d:16,PC)]

 Memory indirect [@@aa:8]

• Address space

 H8/36079 Group: 16 Mbytes

 H8/36077 Group: 64 Kbytes
