Table 14 Allocation of interrupt sources

Notes

1. For some C-compilers ‘1’ has to be added to this number.

2. The interrupt controller supports up to 15 interrupt sources, each with a 2-level (high or low) priority. High priority

interrupt is always serviced before a low priority interrupt, but within the high and low levels, interrupts are serviced

in the order shown in this column.
