Functional Descriptions
The W3000 contains a reference register (REF) and a
main register (MAIN). The REF register is used for
programming the division ratio of the reference clock
and for initial setup of the operation modes. The MAIN
register is intended for programming that can occur
frequently, e.g., dynamic channel switching and
putting the W3000 into power-saving mode.

Figure 6. Register Programming Diagram
Both REF and MAIN registers are programmed
separately, each with a 24-bit data sequence. The last
bit is that which immediately precedes a low-to-high
latch input transition occurring while the CLOCK input
is low. Bit 24 is loaded first, and bit 1 is loaded last.
The last bit in the serial sequence is C0. This bit is
used to direct the 24-bit sequence to the MAIN or REF
registers.

Secondary Address
The first bit, C1, allows the W3000 to share the serial
bus. When C1 is a logic high, the W3000 ignores the
data sent on the serial bus.
