The
microcontroller through a 4-wire SPI port as a slave
device. An SPI-compatible serial interface allows the
user to select, command and monitor the status of the
MRF89XA through the host microcontroller. All
registers are addressed through specific addresses to
control, configure and read status bytes.

The SPI in the MRF89XA consists of the following two
sub-blocks, as illustrated in Figure 2-11:
• SPI CONFIG: This sub-block is used in all data
• SPI DATA: This sub-block is used in Buffered and
First
operation modes to read and write the configuration
registers which control all the parameters of the chip
(operating mode, frequency and bit rate).
Packet mode to write and read data bytes to and
from the FIFO. (FIFO Interrupts can be used to
manage the FIFO content).
