PRODUCTION DATA.
The LOCK command places the converter interface in a locked state where the interface becomes unresponsive to most input commands. The UNLOCK, NULL, RREG, and RREGS commands are the only commands that are recognized when reading back data. Following the LOCK command, the first DOUT status response reads 0555h followed by the command status response of a NULL command (by reading the STAT_1 register). An example showing the response to sending a LOCK command and entering a register locked state is shown in Figure 72.
