Re: pic BANKS

Hi,


The Banks are RAM memory shared by the System and User File Registers.

The more powerfull the chip the more RAM memory / Banks the chips have.

On the 16F chips each bank is typically adressed as 128 bytes although not all 128 bytes in each Bank are available, dependant on the individual chip.

See the respective chips datasheet chart showing the SFR table in the Memory section.

Bank is the technique to enhance the RAM Memory range...

if you have More Flash Memory,More Lines of Code you can store,it needs More RAM to store Data variable

with 8-bit address you can address only 256 byte but bank technique allows you to enhance RAM memory range dependent on the Chip..
