SBASAQ6 April 2024 ADS9813
ADVANCE INFORMATION
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.
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 |
