These are write only registers to configure the device. The registers vary in length to reduce redundant
data and improving the communication speed, especially for SPI and RS232 interfaces. Furthermore, for
SPI and RS232 interfaces, it is vitally important that the length of data written to a register is exact,
because failure to do so will cause the interfaces to misinterpret the incoming data, leaving the device in
a stalled state. A summary of the configuration registers are provided in Table 5, and each register is
explained in detail in the tables following it.
