Section 17 High-Performance User Debugging Interface
(H-UDI)
17.1 Overview
The high-performance user debugging interface (H-UDI) provides data transfer and interrupt
request functions. The H-UDI performs serial transfer by means of external signal control.
17.1.1 Features
The H-UDI has the following features conforming to the IEEE 1149.1 standard.
• Five test signals (TCK, TDI, TDO, TMS, and TRST)
• TAP controller
• Instruction register
• Data register
• Bypass register
• Boundary scan register
The H-UDI has seven instructions.
• Bypass mode
Test mode conforming to IEEE 1149.1
• EXTEST mode
Test mode corresponding to IEEE1149.1.
• SAMPLE/PRELOAD mode
Test mode corresponding to IEEE1149.1.
• CLAMP mode
Test mode corresponding to IEEE1149.1.
• HIGHZ mode
Test mode corresponding to IEEE1149.1.
• IDCODE mode
Test mode corresponding to IEEE1149.1.
• H-UDI interrupt
H-UDI interrupt request to INTC
This chip does not support test modes other than bypass mode.
