H-UDI

H-UDI interrupt source
indication

These bits indicate the interrupt
source of each peripheral module
that is generating an interrupt.
(INT2A1 is affected by the setting
of the interrupt mask register).

0: No interrupt

1: An interrupt has occurred

Note: Interrupt sources can also

be identified by directly
reading the INTEVT code.
In this case, reading from
this register is not required.
