I am wondering how safe it is to use Nigel's bit-banging I2C serial EEPROM routines and interrupts.
The interrupt service routine would not be terribly long; literally on the order of a dozen instructions or so.
I am just worried that if the uC is in the middle of writing something to the serial EEPROM and then an interrupt occured, if the time spent servicing the interrupt would screw up the write.
Any help would be appreciated.
P.S. Great site, Nigel!
