Hi,

   I have some clarification regarding writing and erasing the secured region of cypress flash using SPI from MPC5777c. I have attached the datasheet for the same.

1. Secured region erase can be done as similar to sector erase where the sectors instead of 4k regions we have 256 byte regions to erase and 

2.secure region program is it also similar to page program where the page is programmed on 256 byte boundaries for max of 1024 which means 4 pages. 

could u refer this datasheet and verify whether my understanding is right?

 Thanks in Advance,

Vignesh
