25.4.1.5 GPIO_IRQSTATUS_RAW_1 Register (offset = 28h) [reset = 0h]
GPIO_IRQSTATUS_RAW_1 is shown in Figure 25-11 and described in Table 25-10.
The GPIO_IRQSTATUS_RAW_1 register provides core status information for the interrupt handling,
showing all active events (enabled and not enabled). The fields are read-write. Writing a 1 to a bit sets it
to 1, that is, triggers the IRQ (mostly for debug). Writing a 0 has no effect, that is, the register value is not
be modified. Only enabled, active events trigger an actual interrupt request on the IRQ output line.
