Section 19 User Debugging Interface (H-UDI)
This LSI incorporates a user debugging interface (H-UDI) to provide a boundary scan function
and emulator support.
This section describes the boundary scan function of the H-UDI. For details on emulator functions
of the H-UDI, refer to the user's manual of the relevant emulator.
19.1 Features
The H-UDI is a serial I/O interface which conforms to JTAG (Joint Test Action Group, IEEE
Standard 1149.1 and IEEE Standard Test Access Port and Boundary-Scan Architecture)
specifications.
The H-UDI in this LSI supports a boundary scan function, and is also used for emulator
connection.
When using an emulator, H-UDI functions should not be used. Refer to the emulator manual for
the method of connecting the emulator.
