ADVANCE INFORMATION
The user-defined alternating test pattern allows the host to specify two fixed 24-bit values that are output by the ADS921x alternately. Configure the registers in bank 1 to enable the user-defined alternating test pattern:
The ADS921x outputs the TEST_PAT0_CHA and TEST_PAT0_CHB register values in place of the ADC A and ADC B data, respectively, in one output frame and the TEST_PAT1_CHA and TEST_PAT1_CHB register values in the next frame.
