Execution of an unused area of Flash memory
Accidently if an unused area (data at 0XFFFF) of Flash memory is executed in an instruction, no break can
be accepted. To avoid this, it is recommended to use the code event address mask feature of the debugger
to break at instruction access to the unused area.
Interrupt handler for NMI request (tool)
Add the following program to the interrupt handler to prevent the device from malfunctioning when the source
flag is set accidently with no ICE connected, for example, due to noise to the DSU pin, which is to be set only
at the break request of the ICE. can be used normally with this program added.
Add place :
Next interrupt handler
Interrupt source : NMI request (tool)
Interrupt number : 13 (decimal) , 0D (hexadecimal)
Offset : 3C8H
TBR default address : 000FFFC8H
Add program
STM (R0, R1)
LDI #0B00H, R0
; 0B00H is the address of DSU break source register
LDI #0, R1
STB R1, @R0
; Clear the break source register
LDM (R0, R1)
