AT86RF230
This section describes the AT86RF230 to microcontroller interface. The interface
comprises a slave SPI and additional control signals, see Figure 6-1. The SPI timing
and protocol are described.
Figure 6-1. Microcontroller to AT86RF230 Interface
Microcontrollers with a master SPI, such as Atmel’s AVR family, interface directly to the
AT86RF230. The SPI is used for Frame Buffer and register access. The additional
control signals are connected to the GPIO/IRQ interface of the microcontroller. Table
6-1 introduces the radio transceiver I/O signals and their functionality.
