Note:Read-modify-write instructions, such as a bit manipulation, cannot access ATAS or ATKEY register because
these register are write only.

detecting SYSCR2<XEN> = 0, SYSCR2<XEN> = SYSCR2<SYSCK> = 0 or SYSCR2<SYSCK> = 1, the
device automatically generates an internal reset signal to let the system clock continue oscillating.

・ To prohibit the address trap:
the address trap control registers. When using development tools, even if the address trap permission/
prohibition setting is changed in the user’s program, this change is ineffective. To execute instructions
from the RAM area, development tools must be set accordingly.
program counter is incremented to point to the next address in the address trap area; an address trap is
therefore taken immediately.

Write control code to prohibit
address trap
-
1. Modify the iram (mapping attribute) area to (00040H to 000BFH) in the memory map win-
2. Set 000C0H to "address trap prohibition area" as a new eram (mapping attribute) area.
3. Load the user program
4. Execute the address trap prohibition code in the user’s program
dow.
