Programming
A two-line bus is used to program the circuit; the two lines
being CLKIN and REGIN. The 2-line serial bus interface
allows control over the frequency dividers and the selective
powering up of Tx, Rx and Synthesizer circuit blocks. The
Micrel
interface consists of an 80-bit programming register. Data is
entered on the REGIN line with the most significant bit first.
The first bit entered is called p1, the last one p80. The bits in
the programming register are arranged as shown in Table 1.
