26.4
Boundary scan has the following four registers. These registers cannot be accessed from the CPU.
• Introduction register (JTIR)
• Bypass register (JTBPR)
• Boundary scan register (JTBSR)
• IDCODE register (JTIDR)
Instructions can be input to the instruction register (JTIR) via the test data input pin (TDI) by
serial transfer. The bypass register (JTBPR), which is a 1-bit register, is connected between the
TDI and TDO pins in BYPASS mode. The boundary scan register (JTBSR), which is a JTBSR-bit
register (see table 26.4), is connected between the TDI and TDO pins when test data are being
shifted in. None of the registers is accessible from the CPU.
Table 26.2 shows the availability of serial transfer for the registers.
