XGATE Request Enable — This bit determines if the associated interrupt request is handled by the CPU or by
the XGATE module.
0 Interrupt request is handled by the CPU
1 Interrupt request is handled by the XGATE module
Note: The IRQ interrupt cannot be handled by the XGATE module. For this reason, the configuration register
Interrupt Request Priority Level Bits — The PRIOLVL[2:0] bits configure the interrupt request priority level of
the associated interrupt request. Out of reset all interrupt requests are enabled at the lowest active level (“1”)
to provide backwards compatibility with previous HCS12 interrupt controllers. Please also refer to
available interrupt request priority levels.
