MC68HC908JB8•MC68HC08JB8•MC68HC08JT8 — Rev. 2.3
Freescale Semiconductor
NOTE:
Use the following procedure to erase the entire FLASH memory:
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 as shown, but other unrelated operations
may occur between the steps.
1. Set both the ERASE bit and the MASS bit in the FLASH control
2. Write any data to any FLASH address within the address range
3. Wait for a time, t
4. Set the HVEN bit.
5. Wait for a time t
6. Clear the ERASE bit.
7. Wait for a time, t
8. Clear the HVEN bit.
9. After time, t
