4. Register description
4.1 General Remarks
The entire communication with the device is performed by reading from and writing to
registers. Registers have a width of 8 bits. There are several registers which are either
completely or partially marked as ‘reserved’. Any reserved bit is ignored when it is written and
no specific value is guaranteed when read. It is recommended not to use registers at all
which are completely marked as ‘reserved’. Furthermore it is recommended to mask out
(logical and with zero) reserved bits of registers which are partially marked as reserved.
Read-Only Registers are marked as shown in Table 4-1: Register Access Coding. Any
attempt to write to these registers is ignored.
There are bits within some registers that trigger internal sequences. These bits are
configured for write-only access and read as value ´0´.
