Interrupts from external devices can be indicated in the Interrupt Status Register (ISTA)
of the IPAC.
The auxiliary pins AUX6 and 7 can be configured as general I/O pins and as inputs they
can generate a maskable interrupt to the host (INT0, 1). The host can configure whether
the interrupt on these pins is edge or level triggered.
In contrast to all other interrupt sources in the ISTA register, INT0 and INT1 are masked
(MASK register) after reset.
