• AVR Memory Contents After Sleep and Reset - The AVR contains volatile memories like SRAM, IO registers and the register file with 32 general-purpose registers. What happens to the contents in these volatile memories during a power up reset, an external reset, after a watchdog reset, or when waking up from sleep? This text will describe what contents you can expect to find there. - Added: 28-Aug-2003
