AT86RF212
This section describes the AT86RF212 to microcontroller interface. The interface
comprises a slave SPI and additional control signals; see Figure 4-1. The SPI timing
and protocol are described below.
Figure 4-1. Microcontroller to AT86RF212 Interface
Microcontrollers with a master SPI such as Atmel’s AVR family interface directly to the
AT86RF212. The SPI is used for register, Frame Buffer, SRAM, and AES access. The
additional control signals are connected to the GPIO/IRQ interface of the
microcontroller. Table 4-1 introduces the radio transceiver I/O signals.
