9.5.1 Current Overload

The maximum output current allowed from the Power Amplifier can be programmed with the external RSET resistor connected between PA_ISET (pin 46) and ground. If a fault condition should occur and cause an overcurrent event for the PA, the PA goes into current limit and the I_FLAG bit (location 6 in the RESET Register) is set to a '1' if the I_Flag_EN bit (location 6 in the Control2 Register) is enabled. This configuration results in an interrupt signal at the INT pin. The I_FLAG bit remains set to '1' even after the device returns to normal operation. The I_FLAG bit remains at '1' until it is reset by the microprocessor.

If the I_FLAG_EN bit (location 6 in the Control2 Register) is disabled and a current overload condition occurs, the PA goes into current-limit mode to protect the AFE030; however, the contents of the I_FLAG bit (location 6 in the RESET Register) remain at the respective previous values (presumably '0' for normal operation), and the AFE030 does not issue an interrupt at the INT pin.
