Memory can be written while the CPU is executing, which can be utilized for debug purposes.
When downloading a new program, the JTAG HALT instruction should be used to freeze the
CPU, to prevent partially downloaded code from being executed.
The implemented JTAG instructions in the AVR32 are shown in the table below.
When the security fuse in the Flash is programmed, the following JTAG instructions are
restricted:
• NEXUS_ACCESS
• MEMORY_WORD_ACCESS
• MEMORY_BLOCK_ACCESS
• MEMORY_SIZED_ACCESS
