Programming Description
CONTROL REGISTER CONTENT MAP
The serial interface has a 24-bit shift register to store the incoming data bits temporarily. The incoming Data is loaded into the shift
register from MSB to LSB. The Data is shifted at the rising edge of the Clock signal. When the Latch Enable signal transitions from
LOW to HIGH, the data stored in the shift register is transferred to the proper register depending on the address bit settings. The
selection of the particular register is determined by the control bits indicated in boldface text.
At initial start-up, the MICROWIRE loading requires 4 default words (registers R3, loaded first, to R0, loaded last).After the device
has been initially programmed, the RF VCO frequency can be changed using a single register (R0). If an IF frequency other than
the default value for the device is desired the SPI_DEF bit should be set to 0, the desired values for IF_A, IF_B, and IF_R entered
and words R6 to R0 should be sent.
The control register content map describes how the bits within each control register are allocated to the specific control functions.
