3. EXTEST
4. IDCODE
26.5.2
1. Boundary scan mode does not cover clock-related signals: EXTAL2, XTAL2, EXTAL,
2. Boundary scan mode does not cover the reset-related signal: RESETP.
3. Boundary scan mode does not cover H-UDI-related signals: TCK, TDI, TDO, TMS, TRST,
4. Boundary scan mode does not cover some Bluetooth (BT) related signals: RDI_TXTRDATA,
5. Boundary scan mode does not cover the test-related signal: TEST_REG, TEST.
6. Boundary scan mode does not cover analog signals: USB_P, USB_N, DA0, DA1.
7. When the EXTEST command is set, fix the RESETP pin low.
8. While boundary scan is being executed, fix the ASEMD0 pin high.
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 instruction code is B'000.
The H-UDI pins can be entered in IDCODE mode which is defined by the JTAG by setting the
command to SDIR from the H-UDI pins. When the H-UDI is initialized (when the TRST pin is
asserted or the TAP controller is transited to the Test-Logic-Reset state), IDCODE mode is
entered.
The instruction code is B'100.
