Section 1 Overview
1.1 Features
The features of this LSI are shown below.
CPU:
• Central processing unit with an internal 32-bit RISC (Reduced Instruction Set Computer)
architecture
• Instruction length: 16-bit fixed length for improved code efficiency
• Load-store architecture (basic operations are executed between registers)
• Sixteen 32-bit general registers
• Five-stage pipeline
• On-chip multiplier: Multiplication operations (32 bits × 32 bits → 64 bits) executed in two to
five cycles
• C language-oriented 62 basic instructions
Note: Some specifications on the slot illegal instruction differ from the conventional SH2 core.
For details, see section 5.8, Usage Notes, in section 5, Exception Handling.

• Address, data value, access type, and data size are available for setting as break conditions
• Supports the sequential break function
• Two break channels
U memory:
• 4 kbytes
Cache memory:
• Unified cache, mixture of instructions and data
• 4-way set associative type
• Selection of write-back or write-through mode
