EPCS16 write one byte more than once

Hi, I'm trying to use the EPCS16 as storage memory for few bytes. The configuration is: Use Mega Function ALTASMI_PARALLEL without NIOS. I managed to read and write one byte the first time....

Review the serial flash datasheet: After erasing a 512 kbit sector, you can only change data bits from '1' to '0' when wrring one or multiple bytes with a page program command.
