Section 22 User Debugging Interface (H-UDI)

This LSI incorporates a user debugging interface (H-UDI) and advanced user debugger (AUD) for

a boundary scan function and emulator support.

This section describes the H-UDI. The AUD is a function exclusively for use by an emulator.

Refer to the User’s Manual for the relevant emulator for details of the AUD.

22.1

Features

The H-UDI (User debugging interface) 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 mode, 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.

Figure 22.1 shows a block diagram of the H-UDI.
