5.1 Chip Storage Space Configuration
The storage space of the CMT2380F16 is divided into the 3 categories.
AP space: used to store client applications and data. This part of the data can be erased, read and written by the
programmer and ISP program.
IAP space: It is a non-volatile data storage space that can be used as an EEPROM. This part of the data can be erased,
read and written by the programmer, ISP program and AP application.
ISP space: It is a special storage space, where program code can run independently. It is generally used for online
programming of AP and IAP space, and the storage space of ISP itself can only be programmed by the programmer.
CMT2380F16 provides a total of 8 Kbytes (0000h ~ 1FFFh) storage space as shown in the below figure.
Figure 25. CMT2380F16 Storage Space
The ISP space is configured by the user through the programmer with ISP space ranging from 0 kbytes to 3.5
kbytes. As the IAP space and AP space of the CMT2380F16 are shared, apart from the ISP space, the rest of
8K space is the AP and IAP space.
