Hi Jan,

Thanks for the help. My engineering works become easier with the helps from you guys.

I must admit that I really had the hard time to study philipps datasheet with all these grey area.

I will go to your suggested forum to further discuss my problem.

I'm using flash magic too, I will come back to this forum later ..

Hi Joe,

Thanks for your help.

Sorry, I do not sure that which forum I should go to raise my IAP question. Came to this forum, hopefully could find helps from the experts like you.

Now I know interrupt is not an option to add to the routines with IAP access. I got to find another way to receive data from serial port, i have no idea how to receive serial data without using serial interrupt. Any idea?

Joe, do your mind telling me that what is the access time to write a byte to flash rom using IAP? I could get this information from datasheet.

Thank you,

Kelvin

I have written IAP routines for data writing and reading in flash memory.  The routines work fine, it able to write to and read back the data from the internal flash rom.

My problem is when there is serial interrupt occurs, during the program access the IAP routine; the mcu execution will hang and never get back to the main ruotine again.

Can anyone show me how to avoid this problem.

Thanks in advance.
