wi.dp1205-xxx-r datasheet 10 4. functional description the wi.dp1205-xxx-r is a cost effective high performanc e radio transceiver module designed for the wireless transmission of digital information over distances up to 8 km. the module is based on the rf transceiver circuit from semtech, the truerf tm xe1205. for more information on the xe1205, please refer to the datasheet, available from the semtech website: http://www.semtech.com . the module also incorporates an antenna switch and a saw filter placed on the rx path. figure 2: antenna switch chapter 4
wi.dp1205-xxx-r datasheet 11 5. data operation modes the xe1205 is user-programmable between two modes of operation: continuous mode : each bit transmitted or received is accessed directly at the data input/output pin. buffered mode : a 16-byte fifo is used to store each data byte transmitted or received. this data is written to/read from the fifo via the spi bus. it reduces processor overhead and reduces connections (the data input/output pin is not used in this operation mode) in receiver mode, two lines are dedica ted to interrupt information. the interrupt pins are irq0 and irq1. irq0 has 3 selectable sources. irq1 has 2 selectable sources. the two following tables summarize the interrupt management. irqparam rx irq 0 mcparam buffered mode irq0 irq0 interrupt source 00 1 output no interrupt available 01 1 output write_byte 10 1 output /fifoempty 11 1 output pattern 00 0 output pattern 01 0 output rssi_irq 10 0 output pattern 11 0 output pattern table 4, irq0 interrupt sources in receive mode irqparam rx irq 1 mcparam buffered mode irq1 irq1 interrupt source 00 1 output no interrupt available 01 1 output fifofull 10 1 output rssi_irq 11 1 output rssi_irq 00 0 output dclk 01 0 output dclk 10 0 output dclk 11 0 output dclk table 5, irq1 interrupt sources in receive mode for more information about the data operation modes, please refer to the xe1205 datasheet chapter: description. you can find this at http://www.semtech.com . chapter 5
wi.dp1205-xxx-r datasheet 12 6. serial control interface the xe1205 contains two spi-compatible serial interfaces , one to send and read the chip configuration, the other to send and receive data in buffered mode. both interfaces are configured in slave mode and share the same pins miso (master in slave out), mosi (master out slav e in), sck (serial clock). two additional pins are required to select the spi interface: nss_config to change or read the transceiver co nfiguration, and nss_data to send or read data. figure 3 show the connections between the transceiver and a microcontroller when buffered mode is used. figure 3: serial control interface chapter 6
wi.dp1205-xxx-r datasheet 13 7. operating modes by default, the serial control interface is used for confi guration. it is also possible to change between the four modes (sleep, stand-by, receive, transmit) by using the two-bit signal sw (1:0). this option is enabled by setting the bit mcparam_select_mode to ?1? in the configuration register. if mcparam_select_mode is lo w, the modes are defined by the regist er through the spi_co nfig interface and sw(1:0) may be used as an output to control, for example, an antenna switch. mcparam_select_mode bit 5, address 0 switch (pin) sw(1:0) mcparam_chip_mode bit 7-6, address 0 set in output sleep mode -> sw(1:0) = ?00? 00 ->sleep mode receive mode -> sw(1:0) = ?01? 01 -> receive mode transmitter mode -> sw(1:0) = ?10? 10 -> transmitter mode 0 stand-by mode -> sw(1:0) = ?00? 11 -> stand-by mode sw(1:0) = 00 ->sleep mode sw(1:0) = 01 -> receive mode sw(1:0) = 10 -> transmitter mode 1 sw(1:0) = 11 -> stand-by mode x table 6, operating modes chapter 7
