Programming Description
2.0 INPUT DATA REGISTER
The 24-bit input data register is loaded through the MICROWIRE Interface. The input data register is used to program the control
registers. The data format of the 24-bit data register is shown below. The control bits (CTL[2:0]) decode the internal register
address and the data bits (DATA[21:0]) are used to program various control words for the synthesizer. On the rising edge of LE,
data stored in the input date register is loaded into one of the 8 appropriate latches (selected by control bits). Data is shifted in
MSB first

2.1 REGISTER LOCATION TRUTH TABLE
The control bits CTL[2:0] decode the internal register address. The table below shows how the control bits are mapped to the
target control register.

2.2 CONTROL REGISTER CONTENT MAP
The control register content map describes how the bits within each control register are allocated to specific control functions. The
bits that are marked “0” should be programmed as such to insure proper device operation. It is important to note that some control
words are dual mapped and take one a different control function depending on the operating mode of the device.
