Interrupt (S12XINTV2)
6.1
The XINT module decodes the priority of all system exception requests and provides the applicable vector
for processing the exception to either the CPU or the XGATE module. The XINT module supports:
Each of the I bit maskable interrupt requests can be assigned to one of seven priority levels supporting a
flexible priority scheme. For interrupt requests that are configured to be handled by the CPU, the priority
scheme can be used to implement nested interrupt capability where interrupts from a lower level are
automatically blocked if a higher level interrupt is being processed. Interrupt requests configured to be
handled by the XGATE module can be nested one level deep.

The HPRIO register and functionality of the original S12 interrupt module
is no longer supported, since it is superseded by the 7-level interrupt request
priority scheme.
