RC_A9101-F4_x3_915MHz Band Ref. Code for FIFO mode CL=18pF_V0.5 - RSSI For TX power.zip

1. Set wanted FRXLO.

2. Set RSS= 1 (081Fh), FSARS= 0 (0822h, 4.096MHz ADC clock).

3. Enable ARSSI= 1 (0802h).

4. Send RX Strobe command.

5. In RX mode, 8-times average a RSSI measurement periodically.

6. Exit RX mode, user can read digital RSSI value from ADC [7:0] (0821h) for TX power.

In step 6, if A9101 is set in direct mode, MCU shall let A9101 exit RX mode within 40 us to prevent RSSI inaccuracy
