6.3.6 Test Patterns for Data Interface

The ADS9813 features test patterns used by the host for debugging and verifying the data interface. The test patterns replace the ADC output data with predefined digital data. Enable the test patterns by configuring the corresponding register addresses 0x13 through 0x1B in bank 1.

Table 6-6 lists the test patterns supported by the ADS9813.

Table 6-6 Test Pattern Configurations
ADC OUTPUT TP_EN_CH[4:1]
TP_EN_CH[8:5]		 TP_MODE_CH[4:1]
TP_MODE_CH[8:5]		 SECTION RESULT1
ADC conversion result 0
Fixed pattern 1 0 or 1 Fixed Pattern CH[4:1] = TP0_A
CH[8:5] = TP0_B
Digital ramp 1 2 Digital Ramp CH[4:1] = Digital ramp
CH[8:5] = Digital ramp
Alternating test patterns 1 3 Alternating Test Pattern CH[4:1] = TP0_A, TP1_A
CH[8:5] = TP0_B, TP1_B
Note:
  1. Configure the test patterns for two separate channel groups CH[4:1] and CH[8:5].
