S1M8662A (Preliminary)
CONTROL REGISTERS
S1M8662A has various registers which can be programmed by the SPI bus. These registers have their own
function which are described below.

Reset.
Reset S1M8662A and all the register values are returned
to their default value.
SPI_ID.
Each slave device has its own, independent code;
S1M8662A code is 1E.
BLOCK_CTL
Decides on the S1M8662A operation mode. LO division
ratio. Controls VCO output.
FILTER_SEL.
Lowpass filter selection
VCO_CTL.
Controls the VCO operation and VCO output.
When the master uses this register, the S1M8662A
returns all the programmed register values to their initial
value.
This read-only register is used to confirm the type of
slave connected to the master. It is set to 1Eh and all
S1M8662A has the same value. This is the ID absolutely
required to differentiate the controller from the data,
when there are many slaves connected to the SPI bus.
