PRODUCTION DATA
By default after reset, the device outputs 11-bit data on the Dxx13P, Dxx13M and Dxx3P, Dxx3M terminals and OVR information on the Dxx0P, Dxx0M terminals. When the ALWAYS WRITE 1 bits are set, the ADC outputs 13-bit data on the Dxx13P, Dxx13M and Dxx1P, Dxx1M terminals and OVR information on the Dxx0P, Dxx0M terminals. To enable 14-bit resolution, the DIS OVR ON LSB register bit must be set to 1 as indicated in Table 9-1.
