Data and Configuration Interface
The user interface of the MICRF405 is a serial
peripheral interface (SPI) consisting of Serial
interface enable (SEN), Serial data input/output
(SIO) and Serial clock (SCK). This user interface is
used for MICRF405 configuration setup and can
also be used for sending the user data. A second
option is to transmit data bitwise using the DATAIN
pin. The RDY/DATACLK pin is used to synchronize
the data transfers.
The control word consists of 30 addressable bytes
and defines the way of operations as well as
transmitting data. Table 1 shows all 30 bytes. The
values specified are the default setup, which are
preset after power up. The first register is the

Data
desktop register controlling the state of the 405, the
PA and clock-out for the microcontroller. The next
block of 10bytes sets the output radio frequency
through the dividers A, N and M. The bytes with
address 11 to 21 set the frequency band, modulation
type, bit rate, loop filter type and bandwidth, XCO
tuning etc. This block is not frequently used as these
settings are usually static application dependent.
Address 22 and 23 are mostly test bits, and are
seldom altered from default settings in applications.
The interrupt register, which is located at address
24, is read only (writing to it will not do any harm or
have any effect). The last 5 bytes are used when
transferring user data to transmit through the SPI.
The first four set the SyncID field in the packet, and
the last is the one byte data buffer.
