Section 21 User Debugging Interface (H-UDI)
Rev. 5.00 May 29, 2006 page 565 of 698
REJ09B0146-0500
Data loaded into the output pin boundary scan register in the Capture-DR state is not used for
external circuit testing (it is replaced by a shift operation).
The instruction code is 0000.
21.5.2
Notes for Boundary Scan
1. Boundary scan mode does not cover clock-related signals (EXTAL, EXTAL2, XTAL,
XTAL2, CKIO).
2. Boundary scan mode does not cover reset-related signals (
RESETP
,
RESETM
, CA).
3. Boundary scan mode does not cover H-UDI-related signals (TCK, TDI, TDO, TMS, TRST).
4. When a boundary scan test is carried out, ensure that the CKIO clock operates constantly.
The CKIO frequency range is as follows:
Minimum: 1 MHz
Maximum: Maximum frequency for respective clock mode specified in the CPG section
Set pins MD[2:0] to the clock mode to be used.
After powering on, wait for the CKIO clock to stabilize before performing a boundary scan
test.
5. Fix the
RESETP
pin low.
6. Fix the CA pin high, and the
ASEMD0
pin low.
21.6
Usage Note
1. An H-UDI command other than an H-UDI interrupt, once set, will not be modified as long as
another command is not re-issued from the H-UDI. An H-UDI interrupt command, however,
will be changed to a bypass command once set.
2. Because chip operations are suspended in standby mode, H-UDI commands are not accepted.
However, the TAP controller remains in operation at this time.
3. The H-UDI is used for emulator connection. Therefore, H-UDI functions cannot be used when
using an emulator.
21.7
Advanced User Debugger (AUD)
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.
