Description
The pin is configured according to the I/O registers. See 12.4.7
Reserved
Preamble Quality Reached. Asserts when the PQI is above the programmed PQT value.
Clear channel assessment. High when RSSI level is below threshold (dependent on the current
CCA_MODE setting)
Reserved
Carrier sense. High if RSSI level is above threshold.
CRC_OK. The last CRC comparison matched. Cleared when entering/restarting RX mode.
Reserved
RX_HARD_DATA[1]. Can be used together with RX_SYMBOL_TICK for alternative serial RX output
RX_HARD_DATA[0]. Can be used together with RX_SYMBOL_TICK for alternative serial RX output
Reserved
PA_PD. Can be used to control an external PA or RX/TX switch. Signal is asserted when the radio
enters TX state and de-asserted when the radio exits TX state. The signal is active low
LNA_PD. Can be used to control an external LNA or RX/TX switch. Signal is asserted when the radio
enters RX state and de-asserted when the radio exits RX state. The signal is active low
RX_SYMBOL_TICK. Can be used together with RX_HARD_DATA for alternative serial RX output.
Reserved
HW to 0 (HW1 achieved by setting GDOx_INV=1). Can be used to control an external LNA/PA or
RX/TX switch.
