The default device ordering number is SMH4046FC-232. It is programmed with the register contents as shown above
and tested over the commercial temperature range. New device suffix numbers are assigned to non-default
requirements.
Note 1 – Two sets of configuration registers R84, R8B and R8D are at different slave addresses, address space 1001
and programmable slave address space 101X. The contents shown on the left side of the table are for address 101X.
On the right side at slave address 1001, the contents are 07, 00 and 00.
