Block Write; Calculating Block size

Hi Joshua,

Joshua Einstein said:

I'm seeing conflicting data on what the actual block size is in an MSP430 device. We're using an MSP430F5308, and the Flash memory manual says that the flash is written in 128-byte rows, but on the wiki (http://processors.wiki.ti.com/index.php/Flash_(MSP430)), it says that data is written in 64-byte blocks. 

I think the wiki page content is pretty old and hasn't been updated yet. The 64 byte block size refers to the flash memory controller in the older 1xx, 2xx, 4xx devices (you can check the 1xx, 2xx, 4xx family users guide). For the 5xx, the block size is indeed 128 bytes, which i have tested before.

Hope this helps.
