Hello @DavidT191624
There are a few points I need to explain to you:
1. Normal events are indicated over IRQ. Two registers do exist to handle the events from a host microcontroller which are EVENT_ENABLEand EVENT_STATUS.
• EVENT_ENABLE => register, enables/disables specific event notifications
• EVENT_STATUS => content of this register is part of the event message payload
Which events can be enable, please refer to the Table 19. IRQ EVENT LIST of datasheet.
2. The Command used for loading a dedicated RF protocol is LOAD_RF_CONFIGURATION (0Dh). This instruction is used to load the RF configuration from EEPROM into registers.
So based on the above two points, if you want to trigger an event represented by the IRQ, you need to configure the EVENT_ENABLE register to enable this event. Obviously, LOAD_RF_CONFIGURATION is not on the list of trigger events, so it is recommended that you try the following steps.
-> Setting EVENT_ENABLE.bit4 = RFON_DET_EVENT
-> Executes LoadProtocol command.
-> Switches the RF filed ON.
Thank you for your interest in NXP Semiconductor products and for the opportunity to serve you.
Best regards,
