These reserved registers are designed for factory test purposes only and are
not intended for general user access. Writing to these registers when in
special mode can alter the module’s functionality.
If the input is driven to active level (IRQ=0) a write access to set either
IRQCR[IRQEN] and IRQCR[IRQE] to 1 simultaneously or to set
IRQCR[IRQEN] to 1 when IRQCR[IRQE]=1 causes an IRQ interrupt to be
generated if the I-bit is cleared. Refer to
