5.10. Precautions on debugging functions in the external and extended external areas

The following debugging functions may not properly be performed in the external and extended

external areas:

(a) Storing target program to memory after downloading

(b) Rewriting memory

This problem occurs if the following three conditions are all satisfied:

(1) The target MCU belongs to any of the following MCU groups:

* the 3212x groups

* the 3217x groups

* the 3218x groups

* the 3219x group

(2) The chip operation mode of the target MCU is either of the following:

* processor mode

* MPU mode

(3) The external or extended external area concerned overlaps with the internal ROM area, as

denoted by A in the memory map below.

5.11. About using cast operators for the member variable

When you use cast operators for the member variable to refer to it as the pointer of the structure,

you would not refer to it correctly.
