System Integration Module (SIM)
9.8.1.1
There are seven general purpose inputs, those associated with GPIO-READ(6:0), have interrupt capability.
On every low-to-high edge transition of these inputs, one of the bits 0–6 of register GPIO-INT-STAT is
set. On every high-to-low edge of the inputs, one of the bits 8–14 is set. Write 1 to clear to the
corresponding bit in GPIO-INT-CLEAR register. If any bit in GPIO-INT-STAT is set, and the
corresponding bit in GPIO-INT-EN is set, an interrupt will be made pending on the secondary interrupt
controller.
Set the GPIO_FUNCTION register bit to 1 or 0 for interrupts, as applicable.

General Purpose Input Interrupts
MCLK1 will output a clock signal just after reset and before it can be
configured as a GPIO if so desired. The frequency of the clock will be the
same as CRIN prior to initialization of the PLL.
EBUOUT1 will output a clock signal just after reset and before they can be
configured as GPIO. The frequency of the clock output will be CRIN/16.
These two pins can still be used for GPIO. The user needs to ensure that
when one of these two pins is assigned as a GPIO control within the system,
that its use will not cause the application to exhibit problems when the clock
is active just after reset and before the boot code sets them to GPIO mode,
e.g., do not use these pins to switch a critical circuit on/off.
The registers GPIO-INT-STAT, GPIO-INT-CLEAR and GPIO-INT-EN also
control some audio interrupts.
