Description

-

When the master uses this register, the S1M8662A

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 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.
