6. Any memory location can be verified by using the Read instruction which returns the con-  
tent at the selected address at serial output MISO.  
7. At the end of the programming session, RESET can be set high to commence normal  
operation.  
8. Power-off sequence (if needed):  
Set RESET to “1”.  
Turn VCC power off.
