GUIDELINES FOR UPGRADING FROM THE ST92F120 (0.50 µm) TO THE ST92F124...

Table 6. Memory Structure for 64K ST92F124/F150/F250 Flash device

Since the user reset vector location is set at address 0x000000, the application can use sector

F0 as an 8-Kbyte user bootloader area, or sectors F0 and F1 as a 16-Kbyte area.

new register addresses are:

– FCR

0x221000 & 0x224000

– ECR

0x221001 & 0x224001

– FESR0

0x221002 & 0x224002

– FESR1

0x221003 & 0x224003

In the application, these register locations are usually defined in the linker script file.
