Hi!

Here is the solution to use code banking. For eg. we want to use 8 code banks.

1. 8 code banks ie memory pages.
2. Steps to achive code banking- a. Enable code banking in Startup.a51 file. b. Target options- i. Select code banking. ii. Select no. of banks. iii. Write start & end address of bank area.********** c. Copy L51_bank.a51 file from LIB and modify as per the hardware. d. Modifications in L51_bank.a51- i. ?B_NBANKS = 8 -no. of baks ii. ?B_MODE = 4 -for user defined switch code. iii. Modify the switch code for first 4 banks. iv. Add switch code for remaining 4 banks.
3. If you want to call any function/variable from one bank to other or from common area to bank or vise-versa, those functions/variables have to be imported using keyword "extern".

Best regards, Ishita
