Debug Communication CPU Register (DCCPU)
features on this device. This information is static, and may be used to develop generic Nexus
debuggers which will work across a family of AVR32 devices with different Nexus configurations.
Table 9-6.
If the CPU wants to transmit data to the debugger tool, it writes data to the Debug Communica-
tion CPU Register using mtdr. By writing this register, a dirty bit is set in the Debug
