36.11 SAB address map
Boundary-Scan Chain
Note: This register is primarily intended for compatibility with other AVR32 devices. Certain oper-
ations may not function correctly when parts of the system are reset. It is generally
recommended to only write 0x11111 or 0x00000 to these bits to ensure no unintended side
effects occur.
The Boundary-Scan Chain has the capability of driving and observing the logic levels on the dig-
ital I/O pins, as well as driving and observing the logic levels between the digital I/O pins and the
internal logic. Typically, output value, output enable, and input data are all available in the
boundary scan chain.
The boundary scan chain is described in the BDSL (Boundary Scan Description Language) file
available at the Atmel web site.
The Service Access Bus (SAB) gives the user access to the internal address space and other
features through a 36 bits address space. The 4 MSBs identify the slave number, while the 32
LSBs are decoded within the slave’s address space. The SAB slaves are shown in
Table 36-17. SAB Slaves, addresses and descriptions.
