#98529 - LPC925 - Interrupt Priorities
Hi all

I am just trying to set the interrupt priorities on the LPC925 and the manual has some funnies in it, I was wondering if anyone can explain

in the table below the following interrupts all appear to share the same interrupt priority
EXT Int 0
I2C
KBI
Comparators
Serial Port TX

for instance if I set IP0H.0 and IP0.0 it will affect all of the above interrupts, is this correct?



Then when I get to the SFR registers it appears that the IP0, IP0H, IP1 and IP1H dont match the above table. Any help or clarification would be appreciated.




The manual is the Philips UM10108 P89LPC924/925 Rev.01 28 June 2004

The tables are from pages 10 & 25.

Regards
Marshall Brown
