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
1. Boundary scan mode does not cover clock-related signals (EXTAL, EXTAL2, XTAL,
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.
5. Fix the RESETP pin low.
6. Fix the CA pin high, and the ASEMD0 pin low.
21.6
1. An H-UDI command other than an H-UDI interrupt, once set, will not be modified as long as
2. Because chip operations are suspended in standby mode, H-UDI commands are not accepted.
3. The H-UDI is used for emulator connection. Therefore, H-UDI functions cannot be used when

XTAL2, CKIO).
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.
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.
However, the TAP controller remains in operation at this time.
