Bit | Field | Type | Reset | Description |
---|---|---|---|---|
7 | FIX_PAT | R/W | 0b | Device outputs fixed data bits which can be helpful
for debugging communication with the device. 0b = Normal operation. 1b = Device outputs fixed code 0xA5A repeatitively when reading ADC data. |
6 | RESERVED | R | 0b | Reserved. Reads return 0b. |
5-4 | APPEND_STATUS[1:0] | R/W | 0b | Append 4-bit channel ID or status flags to output
data. 00b: 01b: 10b: 11b: 0b = Channel ID and status flags are not appended to ADC data. 1b = 4-bit channel ID is appended to ADC data. 10b = 4-bit status flags are appended to ADC data. 11b = Reserved. |
3-2 | RESERVED | R | 0b | Reserved. Reads return 0b. |
1-0 | CPOL_CPHA[1:0] | R/W | 0b | This field sets the polarity and phase of SPI
communication. 0b = CPOL = 0, CPHA = 0. 1b = CPOL = 0, CPHA = 1. 10b = CPOL = 1, CPHA = 0. 11b = CPOL = 1, CPHA = 1. |
