7. PHY to Micro-Controller Interface
In the following paragraphs, the PHY to micro-controller interface is defined. The SPI protocol and timing access
are shown, as well as buffer access modes with examples.
Controllers with an SPI interface such as an AVR will work with the AT86RF230 interface. The SPI interface is
used for both register programming as well as for frame transfer. The additional control signals are connected to
the GPIO interface of the controller.
Figure 7-1
shows the signals which need to be connected between the
controller and the transceiver. The CLKM signal can be used as a controller main clock (synchronous mode) or as
software timer reference (asynchronous mode).

PHY-HOST Interface
7.1. SPI Protocol
SPI is used to program control registers as well as to transfer data frames between the controller and the
AT86RF230. The additional signals CLKM, IRQ, SLP_TR and
RST
are connected to the GPIO interface of the
controller.
The internal 128-byte frame buffer can keep one TX or one RX frame of maximum length at a time. This offers a
very flexible data rate over the SPI interface.
