synchronous serial port IRQ


I've been trying to get the slave output mode working for sync serial port 0 on 
the 100LX board and I have been going through the driver sync_serial.c.  There 
are some hardcoded IRQ numbers in calls to request_irq(), particularly 8 for 
non-DMA and 24,25 for DMA.  I'm curious where these IRQ numbers come from. I've 
looked through the Designers Reference Manual but I can't find any mention of 
IRQ lines.  Could someone please give me some guidance.
