Registers and flags description

All device features can be configured through a set of 8-bit long registers.

There are three different types of registers:



Local registers are located on the low voltage side



Remote registers are located on the isolated side



Shared registers are located both on the low voltage and isolated side and the value of

the two copies is kept synchronized.

A map of the user registers is shown in Table 22.
