GPIO2
IO
GPIO2 of RF module; it can be configured as: INT1,INT2,DOUT/DIN,DCLK
(TX/RX),RF_SWT.
40
[2]
GPIO1
IO
GPIO1 of RF module; it can be configured as: DOUT/DIN,INT1,INT2,DCLK
(TX/RX),RF_SWT
Notes:
[1]. INT1 and INT2 refer to RF interrupts. DOUT refers to the demodulated data output. DIN refers to the modulation data
input. DCLK refers to the modulation or demodulation data rate synchronous clock, which is switched automatically
according to operation mode switch between TX and RX.
[2]. The SPI and GPIOn of RF module are not connected to MCU ports. Users need to select the appropriate port of the
MCU for off-chip connection according to application requirements (namely connecting to the PCB board).
