Description
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.
