NOTE:
PGM — Program Control Bit
Use this step-by-step procedure to erase a page (64 bytes) of FLASH
memory to read as logic 1:
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 the ERASE bit, and clear the MASS bit in the FLASH control
2. Read the FLASH block protect register.
3. Write any data to any FLASH address within the page address
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.
Freescale Semiconductor, Inc.
This read/write bit configures the memory for program operation.
PGM is interlocked with the ERASE bit such that both bits cannot be
equal to 1 or set to 1 at the same time.
