A:

Note: This answer applies to devices with F05 flash.  Refer to:  [FAQ] F05 Flash: Which C2000 devices have "F05 flash"?

These operations are described in detail in the Flash API documentation for a specific device: C2000Ware_\libraries\flash_api\\docs\

In summary:

Erase:

• Flash comes from the factory in an erased state.
• The erase algorithm sets all bits to a "1"
• The minimum amount of memory that can be erased is a sector.
• Erase operates on the F05 flash bank and not on the OTP (one-time programmable memory)

Program:

• Program loads application code and/or data into flash by clearing bits in the memory to "0"
• Program cannot move a bit from 0 to 1. 
• Program operates on both the flash bank and the OTP
• Program can operate on a single bit within a 16-bit word.
