30.4.1
In the H-UDI in this LSI, the boundary-scan TAP controller is separated from the TAP controller
for other H-UDI function control. When the TRST is asserted (including when the power is turned
on), the boundary-scan TAP controller operates and the boundary scan function specified in JTAG
can be used. By inputting the switching command, an H-UDI reset and H-UDI interrupts can be
used. However, the following restrictions are put on this LSI.
• Clock-related pins (EXTAL and XTAL) are out of the scope of the boundary scan test.
• Reset-related pin (PRESET) is out of the scope of the boundary scan test.
• H-UDI-related pins (TCK, TDI, TDO, TMS, TRST, AUDSYNC, AUDCK, AUDATA3 to
• DDRIF-related pins are out of the scope of the boundary scan test.
• During the boundary scan (IDCODE, EXTEST, SAMPLE/PRELOAD, BYPASS, and H-UDI
• The access size from the H-UDI to the boundary-scan TAP controller is 8 bits.
The commands supported by the boundary-scan TAP controller are shown below.
Note: During the boundary scan, the MPMD and the PRESET pins should be fixed to high level.

switching command), the maximum frequency of TCK is 10 MHz.
When the H-UDI operates in emulation support mode (MPMD = 0), the boundary scan
function cannot be used. Figure 30.2 shows the sequence to switch from the boundary-
scan TAP controller to the H-UDI.
