4.2.3 FLASH Page Erase Operation
Technical Data

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. Do not exceed t
maximum. See
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 to any FLASH address with any data within the page
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.
This read/write bit configures the memory for program operation.
PGM is interlocked with the ERASE bit such that both bits cannot be
set at the same time.

0 = Program operation unselected
