FLASH Memory
4.6 FLASH Mass Erase Operation
Technical Data
60
NOTE:
Programming and erasing of FLASH locations cannot be performed by
code being executed from the same FLASH array that is being
programmed or erased. While these operations must be performed in
the order as shown, but other unrelated operations may occur between
the steps.
A mass erase operation erases an entire array of FLASH memory. The
MC68HC908LD60 contains two FLASH memory arrays, therefore, two
mass erase operations are required to erase all FLASH memory in the
device. Mass erasing the 13k-byte array, erases all FLASH memory
from $0800 to $3FFF. Mass erasing the 47,616-byte array, erases all
FLASH memory from $4000 to $FFFF.
Use the following procedure to erase an entire FLASH memory array:
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 a time, t
1. Set both the ERASE bit, and the MASS bit in the FLASH control
2. Write any data to any FLASH address within the FLASH memory
3. Wait for a time, t
4. Set the HVEN bit.
