Product data sheet
8.3 Registers
Table 3.
n.c. = not connected
[1]
The device contains more than 9 registers. They are used to store the data of device
set-up and operation results. Depending on the bus communication (either read or write
operations), each register may be called by different names because each register may
have different sub-addresses or commands for read and write operations. For example,
the configuration register is called as WC for write mode and as RC for read mode.
Table 4
POR states.
Remark: Attempting to write to a read-command or read from a write-command will
produce an invalid result. The reserved registers are used for factory test purposes and
should not be written.
