11.6 FLASH Mass Erase Operation
MC68HC908GR8 — Rev 4.0
MOTOROLA
NOTE:
Use this step-by-step procedure to erase entire FLASH memory to read
as logic 1:
* When in Monitor mode, with security sequence failed
block protect register instead of any FLASH address.
Programming and erasing of FLASH locations cannot be performed by
code being executed from the FLASH memory. While these operations
must be performed in the order shown, other unrelated operations may
occur between the steps.
10. After a time, t
1. Set both the ERASE bit, and the MASS bit in the FLASH control
2. Read from the FLASH block protect register.
3. Write any data to any FLASH address* within the FLASH memory
4. Wait for a time, t
5. Set the HVEN bit.
6. Wait for a time, t
7. Clear the ERASE bit.
8. Wait for a time, t
9. Clear the HVEN bit.
