Status checking during flash memory programming and erasing is an embedded algorithm. The status bits are not in an SFR register. Please see page 109-112 for detail information.

Also please see the attached files for a code example on Flash Write using polling method to check for completion. The function is written in C. I also included this function displayed in Disassembly and Mix mode from Keil's compiler.

Hi people.

I want to know how I can read the status bit of Flash Memory (DQ7...DQ0). I don't know if it have a SFR or not.

If is possible to get a description in assembler will be great.

Thank all.
