The DACx3202 contain nonvolatile memory (NVM) bits. These memory bits are user programmable and erasable, and retain the set values in the absence of a power supply. All the register bits, shown in the highlighted gray cells in Section 7.6, can be stored in the NVM by setting NVM-PROG = 1 in the COMMON-TRIGGER register. The NVM-PROG is an autoresetting bit. The default values for all the registers in the DACx3202 are loaded from NVM as soon as a POR event is issued.

The DACx3202 also implement NVM-RELOAD bit in the COMMON-TRIGGER register. Set this bit to 1 and the device starts an NVM-reload operation. After completion, the device autoresets the NVM-RELOAD bit to 0. During the NVM write or reload operation, all read/write operations to the device are blocked. Section 6.8 provides the timing specification for the NVM write cycle. The processor must wait for the specified duration before resuming any read or write operation on the SPI or I²C interface.
