22. User Debugging Interface (H-UDI)
22.3
The H-UDI has the following registers. For the register addresses and register states in each
operating mode, refer to section 25, List of Registers.
• Instruction register (SDIR)
• Status register (SDSR)
• Data register H (SDDRH)
• Data register L (SDDRL)
• Bypass register (SDBPR)
Instructions and data can be input to the instruction register (SDIR) and data register (SDDR) by
serial transfer from the test data input pin (TDI). Data from the status register (SDSR), and SDDR
can be output via the test data output pin (TDO). The bypass register (SDBPR) is a one-bit register
that is connected to TDI and TDO in bypass mode. Except for SDBPR, all the registers can be
accessed by the CPU.
Table 22.2 shows the kinds of serial transfer that can be used with each of the H-UDI’s registers.
