Hi all, I want to read the SRAM power-on value as PUF. Now I am working with Arduino mega and CY62256 SRAM chip. I found the page 27 of datasheet of ATmega 2560, section 9: External Memory Interface

http://www.atmel.com/Images/Atmel-2549-8-bit-AVR-Microcontroller-ATmega640-1280-1281-2560-2561_datasheet.pdf

It looks like the ATmega 2560 contains hardware interface with external SRAM. I want to use it but I do not know how to set up the registers. Anyone could help me or provide some tutorials? Thank you!
