how can i know the vector of a special MCU like SST89E564RD? it provides about 15 interrupts, but how to know which vector is which interrupt?
"the 'Keil interrupt number' must be calculated"
Or you can just look-up the vector address in the Manual: http://www.keil.com/support/man/docs/c51/c51_le_interruptfuncs.htm
oh well, if the calculation is too cumbersome for someone :)
anyhow the warning: many datasheets will state "interrupt numbers" BEWARE. they are often not the "Keil interrupt numbers is still valid.
