3.3. Interrupts
The Si4430/31/32 is capable of generating an interrupt signal when certain events occur. The chip notifies the
microcontroller that an interrupt event has occurred by setting the nIRQ output pin LOW = 0. This interrupt signal
will be generated when any one (or more) of the interrupt events (corresponding to the Interrupt Status bits) shown
below occur. The nIRQ pin will remain low until the microcontroller reads the Interrupt Status Register(s) (Registers
03h04h) containing the active Interrupt Status bit. The nIRQ output signal will then be reset until the next change
in status is detected. The interrupts must be enabled by the corresponding enable bit in the Interrupt Enable
Registers (Registers 05h06h). All enabled interrupt bits will be cleared when the microcontroller reads the
interrupt status register. If the interrupt is not enabled when the event occurs it will not trigger the nIRQ pin, but the
status may still be read at anytime in the Interrupt Status registers.
See AN440: EZRadioPRO Detailed Register Descriptions for a complete list of interrupts.
