// Test:
//   Does Wokwi use the Reset pin and can that be
//   controlled from code and does the red button
//   on the board work and does Wokwi preserve
//   the SRAM contents ?
//
//   Answer to all of that: Yes
//
// An Arduino Uno in real life keeps its unused SRAM contents,
// during a reset.

// Point to a SRAM location that is hopefully never used.
