2. Boot loader application.

3. EEPROM Emulation.

How does this block work?

Input data port:

1. Offset, offset of memory in Flash Sector.

  Example: For Sector 5, memory base is 0x08020000. The actual writing program memory address is 0x08020000 + Offset.

2. Data, input data to write into program memory.

Output data port:

1. Status, this status port is return result of Flash write operation.
