20.1 Embedded Flash
20.1.1 Flash Features
20.1.2 Flash Configuration
Figure 20-1 shows the Flash configuration of MPC82G516A. The Flash an be partitioned into AP-memory, IAP-
memory and ISP-memory. AP-memory is used to store the user’s application program; IAP-memory is used to
store the non-volatile application data; and, ISP-memory is used to store the loader program for In-System
Programming. The total Flash size is 64K bytes, where the space of IAP-memory and ISP-memory can be
configured by a Universal Programmer, the “Megawin 8051 Writer” or the “Megawin 8051 ICP Programmer” (see

The Flash can only perform ‘page’ erasing, not byte erasing. And, the erased page data will become all 0xFF.
Only the byte with value of 0xFF can programmed into a non-0xFF byte. Any non-0xFF byte can not be
reversely programmed into a 0xFF byte unless using the page erasing.
Each page has 512 bytes, and the page address is always located at 0x0200
