Figure 9-7. Frame Transmit Procedure - Transactions between AT86RF230 and
Microcontroller
Alternatively, the frame transmission can be started before the frame data download as
described in Figure 9-8. This is useful for time critical applications. At the rising edge of
SPL_TR, the radio transceiver starts transmitting the preamble and the SFD field, which
takes about 176 µs (see Figure 7-2). The first byte of the PSDU must be available in the
Frame Buffer before this time. The SPI data rate must be higher than 250 kBit/s to
ensure that no Frame Buffer under run occurs (IRQ_6, TRX_UR).
