AT89C51CC03 features two on-chip Flash memories:
The FM0 can be program by both parallel programming and Serial In-System Program-
ming (ISP) whereas FM1 supports only parallel programming by programmers. The ISP
mode is detailed in the "In-System Programming" section.
All Read/Write access operations on Flash Memory by user application are managed by
a set of API described in the "In-System Programming" section.
The bit ENBOOT in AUXR1 register is used to map FM1 from F800h to FFFFh. Figure
23 and Figure 24 show the Flash memory configuration with ENBOOT=1 and
ENBOOT=0.
