Configuration Notes:
The following table gives an overview of the available memory areas in the communications processor CP 343-1 IT and CP343-1 Advanced.

Note:
The flash memory has a limited lifetime with cyclic writing. It is about 70,000 cycles. If you expect a high number of write cycles, you should use the RAM area.
