6. Memory Organization
MG87FE/L2051/4051/6051 device has separate address spaces for program and data memory. On-chip data
memory can be accessed by 8-bit addresses, which can be quickly stored and manipulated by the 8-bit CPU.
Program memory in MG87FE/L2051/4051/6051 can only be read, not written into.
6.1. On-Chip Program Flash
In MG87FE/L2051/4051/6051, the first partition named AP-memory is the space for storing user’s application
program code. The second one named as IAP-memory and the space which is accessed by CPU for storing the
user data. The third is named as ISP-memory and it is special for ISP boot code program.
