The RV bit in the Configuration Register is set to
indicate a valid reset has occurred. The RS bit
should be written back to logic “0” to complete the

caused an operational issue for customers
because their start-up sequence includes
writing a word (with RS=0) into the
configuration register after performing a
reset. The change in the reset sequence to
include writing the RS bit back to 0 insures
the clearing of the RS bit in the event that a
user does not write into the configuration
register after the RS bit has been set.
reset cycle. After a system initialization or reset,
the on-chip controller is initialized into command
mode where it waits for a valid command (the first
8-bits written into the serial port are shifted into the
command register). Once a valid command is re-
ceived and decoded, the byte instructs the converter
to either acquire data from or transfer data to an in-
ternal register(s), or perform a conversion or a cal-
ibration. The Command Register Descriptions
section can be used to decode all valid commands.
