#121165 - C8051f310R flash erase will erase entire page?? |
I was going throught the C8051f31x.pdf and it is mentioned
"A write to FLASH memory can clear bits to logic 0 but cannot set them.Only an erase operation can set bits to logic 1 in FLASH. A byte location to be programmed should be erased before a new value is written. The FLASH memory is organized in 512-byte pages." How can I write an individual byte to the FLASH without erasing the entire page.In the code which I am writing I need to write to the individual bytes of FLASH memory. If the entire page is erased before writing, the previous writes to the memory become useless. Please can anyone give me a solution to this problem. |
