Data sheet
5. Register description
5.1 General remarks
The entire communication with the device is performed by reading from and writing to registers
(exception: dedicated mode, see chapter 4.2.2). Registers have a width of 8 bits; they are
mapped to a common space of 64 addresses from (0x00) up to (0x3F). Within the used range
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’. Further-
more it is recommended to mask out (logical and with zero) reserved bits of registers which are
partially marked as reserved.
Registers with addresses from (0x00) up to (0x0E) are read-only. Any attempt to write to these
registers is ignored. There are bits within some registers that connected with an action to be
done and, therefore, are intended for write-only access, e. g. (0x21) reset_int or the entire
(0x14) softreset register. Such bits always give ´0´ when read.
