Mass Erase
Flash Controller Bypass
Flash Controller Behavior using the On-Chip Debugger
The Flash memory cannot be Mass Erased by user code.
The Flash Controller is bypassed and the control signals for the Flash memory brought out
to the GPIO pins. Bypassing the Flash Controller allows faster Programming algorithms
by controlling the Flash programming signals directly.
Flash Controller Bypass is recommended for large volume gang programming
applications, which do not require in-circuit programming of the Flash memory.
The following changes in behavior of the Flash Controller occur when the Flash
Controller is accessed using the On-Chip Debugger:
•
•
•
•
•
•
•
The Flash Controller does not have to be unlocked for program and erase operations.
The Flash Write Protect option bit is ignored.
The Flash Sector Protect register is ignored for programming and erase operations.
Programming operations are not limited to the page selected in the Flash Page Select
register.
Bits in the Flash Sector Protect register is written to one or zero.
The Flash Page Select register is written when the Flash Controller is unlocked.
The Mass Erase command is enabled.
