3.4
The XC800 Core supports one non-maskable interrupt (NMI) and 14 maskable interrupt
requests. In addition to the standard interrupt functions supported by the core, e.g.,
configurable interrupt priority and interrupt masking, the XC866 interrupt system
provides extended interrupt support capabilities such as the mapping of each interrupt
vector to several interrupt sources to increase the number of interrupt sources
supported, and additional status registers for detecting and determining the interrupt
source.
