21.2.5 Boundary Scan Register (SDBSR) (SH7750R Only)
The boundary scan register (SDBSR) is a shift register that is placed on the pads to control the
chip's I/O pins. This register can perform a boundary scan test equivalent to the JTAG (IEEE Std
1149.1) standard using EXTEST, SAMPLE, and PRELOAD commands. Table 21.3 shows the
relationship between the SH7750R's pins and the boundary scan register.
