CONTROL REGISTERS
S1M8656A has various registers which can be programmed by the SPI bus. These registers have their own
function which are described below.
W : MODEM is recorded in the S1M8656A register R : When S1M8656A sends data to the modem

Reset.
Reset S1M8656A and all the register values are returned
to their default value.
SPI_ID.
Each slave device has its own, independent code;
S1M8656A code is 1Fh.
BLOCK_CTL
Decides on the S1M8656A operation and performs the
same functions as IDLEB, FMB and SLEEPB in the
parallel control mode.
CLK_GEN_MODE
Changes the internal divider(TCXO,CHIPx8) conditions;
controls the output drive.
AGC_DCONV
Controls the AGC gain control range and VCO output.
When the master uses this register, the S1M8656A 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 1Fh and all
S1M8656A 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.
