8 / 25 page 6 Preliminary Product Information U19858EJ1V0PM μPD78F8056, 78F8057, 78F8058 6. CONNECTION BETWEEN MCU AND RF TRANSCEIVER (1) Internal Connection Name RF transceiver MCU Function(RF transceiver) Direction SCLK_RF P10/SCK00 Clock signal of SPI interface MCU → RF transceiver SO_RF P11/SI00 Output signal of SPI interface RF transceiver → MCU SI_RF P12/SO00 Input signal of SPI Interface MCU → RF transceiver SEN_RF P17 Enable signal of SPI interface High level: disable Low level: enable MCU → RF transceiver GPIO2 P15/RTCDIV/ RTCCL Case of using P15/RTCDIV/ RTCCL, set input mode to GPIO2. Case of using GPIO2, set input mode to P15/RTCDIV/RTCCL. − GPIO3 P16/TI01/ TO01/INTP5 Case of using P16/TI01/TO01/INTP5, set input mode to GPIO3. Case of using GPIO3, set input mode to P16/TI01/TO01/INTP5. − (2) Connection externally on the PCB by users Name RF transceiver MCU Function(RF transceiver) Direction RESET_RF P130 RESET input signal for transceiver High level: disable Low level: enable MCU → RF transceiver WAKE_RF P144 Wakeup request signal for transceiver The active level can be specified by software setting at RF transceiver. MCU → RF transceiver INT_RF P31/TI03/ TO03/INTP4 Interrupt output signal The active level can be specified by software setting at RF transceiver. RF transceiver → MCU CLK_OUT P122/X2/ EXCLK Clock out at 32/16/8/4/2/1 MHz. Use system clock MCU. XTAL_P and XTAL_N of RF transceiver is main clock at 32 MHz. RF transceiver → MCU Note These are mandatory connection for recommendation library of our company. The RESET_RF connect to VDD via a resistor of about 10 K ohm. |
