Flash Programming
Flash Programming Basics
 The device CPU performs the flash programming

The CPU executes Flash utility code from RAM that reads the Flash
data and writes it into the Flash
 We need to get the Flash utility code and the Flash data into RAM

Flash Programming Basics

Sequence of steps for Flash programming:
 Minimum Erase size is a sector (8Kw or 16Kw)
 Minimum Program size is a bit!
 Important not to lose power during erase step:
If CSM passwords happen to be all zeros, the
CSM will be permanently locked!
 Chance of this happening is quite small! (Erase
step is performed sector by sector)
1. Erase - Set all bits to zero, then to one
2. Program - Program selected bits with zero
3. Verify - Verify flash contents
