Bit
Configuration Register
15
The configuration register sets up the following:
Bit [15..8] – Command Code: These bits are the command code that is sent serially to the processor
that identifies the bits to be written to the configuration register.
Bit [7] – TX Data Register Enable: This bit enables the internal TX data register when set. If the internal
TX data register is used, the DATA/nFSEL pin (6) must be pulled “High”.
Bit [6] – FIFO Enable: This bit enables the internal data FIFO when set. If the data FIFO is enabled, the
DATA/nFSEL pin (6) must be pulled “Low”. The FIFO is used to store data during receive. If the FIFO is
disabled by clearing this bit, pin 6 (Data) and pin 7 (Recovered Clock) are used to receive data.
Bit [5..4] – Band Select: These bits set the frequency band to be used. There are four (4) bands that are
supported. See Table 3 below for Band configuration.
Bit [3..0] – Load Capacitance Select: These bits set the load capacitance for the crystal reference. The
internal load capacitance can be varied from 8.5pF to 16pF in 0.5pF steps to accommodate a wide range
of crystal vendors as well as adjust the reference frequency and compensate for stray capacitance that
may be introduced due to PCB layout. See Table 4 below for load capacitance configuration.
