Interrupt Enable Auto Clear
This bit configures all interrupt enable bits to clear or not clear after
reading the interrupt status bit.
0= Configures all Interrupt Enable bits to not cleared after reading
the interrupt status bit. The corresponding Interrupt Enable bit will
stay ‘high’ after reading the interrupt status bit.
1= Configures all interrupt Enable bits to clear after reading the
interrupt status bit. The corresponding interrupt enable bit will be set
to ‘low’ after reading the interrupt status bit.
