Note: When operating in the serial I/O mode, it is best to use the
external update mode to avoid an update CLK during serial communication
cycle. Such an occurrence could cause incorrect
programming due to partial data transfer. To exit the default
internal update mode, at power up, before starting the REFCLK
signal program the device for external update operation. Starting
the REFCLK will cause this information to transfer to the register
bank, putting the device in external update mode.
