Hi Guille,

Just to let you know that the IAP looks after everything and I had some 
misgivings about having to hand control over to an IAP. But, as I said, 
it looks after everything. I certainly don't get any inadvertent Flash 
corruption happening.

My software runs from Flash and never has a problem with programming it. 
A little side note though, somewhere between the early IAP in the 2106 
and the latest in the 2138 I had problems. My IAP routines were 
reporting a program failure. It turned out I was assuming that R0,R1 
would stay intact as it had originally, but the new IAP does not restore 
them.

Also, I wish Philips would handle the address to sector translate 
though, otherwise the application interface has to worry about it for 
the different cpu sector maps (petty whinge).
