TMS320F2808: TMS320F2808

Please help me. I need to create firmware running on TMS320F2808
that will receive data by SCI and write them into internal FLASH memory.

Questions:

What is the control data to write and which is the control register
to write the data if I want to set all bits in a sector of FLASH to 0?

What is the control data to write and which is the control register
to write the data if I want to set all bits in a sector of FLASH to 1?

Which is the register to read information about how deep is
over-erasing (depletion) of individual bits in FLASH memory?

What is the control data to write and which is the control register
to write the data if I want to correct the depleted bits of FLASH?

What is the control data to write and which is the control register
to write the data if I want to set individual bits of the FLASH to 0?

Please what is the timing of the above operations in nanoseconds
or microseconds?

Please if you will send me in attachment some technical document
or link to the document describing manipulation of the FLASH memory
in TMS320F2808 you don't need to explain the topic in detail.
