Hello Xiaohui,

I included datasheet extracts giving more information on the MCU direct mode below. But in summary the following must be done:

1. Configure PLLCR3_CODE = 1 to configure direct mode;
2. Configure RFCR2_SEND = 1 to enable the RF output;
3. Wait for RF output stage to be stable by monitoring RFCR7_RCTS bit;
4. Control the RF signal to be high state or low state with RFCR3_DATA bit.

I hope it helps.

Best regards,

Tomas
