The implemented JTAG instructions in the 32-bit AVR are shown in the table below.
When the security fuse in the Flash is programmed, the following JTAG instructions are
restricted:
For description of what memory locations remain accessible, please refer to the SAB address
map.
Full access to these instructions is re-enabled when the security fuse is erased by the
CHIP_ERASE JTAG instruction.
Note that the security bit will read as programmed and block these instructions also if the Flash
Controller is statically reset.

• MEMORY_WORD_ACCESS
• MEMORY_BLOCK_ACCESS
• MEMORY_SIZED_ACCESS
