Flash Controller Behavior using the On-Chip Debugger
4. Write a word to Program memory.
5. Repeat step 4 to program additional memory locations on the same page.
6. Write
The Flash memory is erased one page (2 KB) at a time. Page Erasing the Flash memory
sets all words in that page to the value FFFFH. The Flash Page Select register identifies
the page to be erased. While the Flash Controller executes the Page Erase operation, Flash
reads are held in wait. Interrupts that occur when the Page Erase operation is in progress
will be serviced after the Page Erase operation is complete. When the Page Erase opera-
tion is complete, the Flash Controller returns to its locked state. Only pages located in
unprotected sectors are erased.
The steps to perform a Page Erase operation are:
1. Write the page to be erased to the Flash Page Select register.
2. Write the first unlock command
3. Write the second unlock command
4. Write the Page Erase command
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.
