Notes: 1. Indicates whether the register can be read/written to by the CPU.
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 SDIR, the status register (SDSR), and
SDDR can be output via the test data output pin (TDO). The bypass register (SDBPR) is a 1-bit
register to which TDI and TDO are connected in bypass mode. The boundary scan register
(SDBSR) is a 330-bit register, and is connected to TDI and TDO in the SAMPLE/PRELOAD or
EXTEST mode. The ID code register (SDIDR) is a 32-bit register; a fixed code can be output via
