CONTROL REGISTERS
S1M8660A has various registers which can be programmed by the SPI bus. These registers have their own
function which are described below.

Reset.
Reset S1M8660A and all the register values are
returned to their default value.

SPI_ID.
Each slave device has its own, independent code;
S1M8660A code is 1Fh.
0x3C
BLOCK_CTL
Decides on the S1M8660A operation and performs the
same functions as IDLEB, FMB and SLEEPB in the
parallel control mode.
0x0C
CLK_GEN_MODE
Changes the internal divider(TCXO,CHIPx8) conditions;
controls the output drive.
0x0A
FILTER_SEL
Lowpass filter selection
0x0B
AGC_DCONV
Controls the AGC gain control range and VCO output.

Description
-
When the master uses this register, the S1M8660A
returns all the programmed register values to their initial
value.
[5:0]
This read-only register is used to confirm the type of
slave connected to the master. It is set to 1Fh and all
S1M8660A 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.
