This instruction is provided to test external circuitry when this LSI is mounted on a printed circuit
board. When this instruction is executed, output pins are used to output test data (previously set by
the SAMPLE/PRELOAD instruction) from the boundary scan register to the printed circuit board,
and input pins are used to latch test results into the boundary scan register from the printed circuit
board. If testing is carried out by using the EXTEST instruction N times, the Nth test data is
scanned-in when test data (N-1) is scanned out.
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 upper four bits of the instruction code are B'0000.
(4)
A command can be set in SDIR by the H-UDI pins to place the H-UDI pins in the IDCODE mode
stipulated by JTAG. When the H-UDI is initialized (TRST is asserted or TAP is in the Test-Logic-
Reset state), the IDCODE mode is entered.
(5)
A command can be set in SDIR by the H-UDI pins to place the H-UDI pins in the CLAMP or
HIGHZ mode stipulated by JTAG.

1. Boundary scan mode does not cover the following signals:
2. When the EXTEST, CLAMP, and HIGHZ commands are set, fix the RESETP pin low.
3. Fix the CA pin high, during boundary scan.
4. When a boundary scan test for other than BYPASS and IDCODE is carried out, fix the
 Clock-related signals (EXTAL, XTAL, EXTAL_USB, XTAL_USB, EXTAL_RTC,
 System- and E10A-related signals (RESETP, RESETM, CA, ASEMD0)
 H-UDI-related signals (TCK, TDI, TDO, TMS, TRST)
 IIC-related signals (IIC_SCL/PTE6, IIC_SDA/PTE5)
