Settings for memory protect switch
Memory write protect switch is for prevent a program from overwriting and deletion by an
operation of the peripheral device.
It is used to prevent overwriting and deletion of a program after the program is created.
To modify the ROM memory, cancel the memory write protect (OFF).
Upon shipment, the memory write protect is set to OFF (SW-1 to 9 OFF)
REMARK
When A2SMCA-14KE or A2SNMCA-30KE is used, memory protect is possible
with the memory protect setting pins on the main unit of the A2SNMCA-30KE.
Refer to Section 7.1.4.
POINT
(1) When the memory protect is used, refer to the address (step number) of each
memory area (sequence program, comment, sampling trace, status latch and
file register) to set protection. (Refer to Section 4.2.2)
(2) When sampling trace or status latch is executed, do not apply the memory
protect to the data storage area.
If the protection is applied, the execution results cannot be stored in the
memory.
