I know that any driver for the 91C111 has to force a strobe of the 91C111's chip select between reads/writes so that it doesn't go all wonky on you. The standard practice for generating the strobe seems to be a read of FLASH memory.

But... is there another device / physical memory area I could read instead of FLASH? I ask because I may be running into an issue where network activity occurs while I'm trying to program the FLASH, and I'd rather not have spurious FLASH reads occur during my write/erase transactions.

I would like to avoid blocking interrupts while doing FLASH operations, if I can. So... is there a less intrusive area I could access to force the strobe?

Thanks.
