Bit | Field | Type | Reset | Description |
---|---|---|---|---|
15 | OFFSET_REMOVAL_SELF | R/W | 0h | Auto offset removal mode is enabled when this bit is set to 1 |
14 | OFFSET_REMOVAL_START_SEL | R/W | 0h | 0 = Auto offset correction initiated when the OFFSET_REMOVAL_START_ MANUAL bit is set to 1.
1 = Auto offset correction initiated with a pulse on TX_TRIG pin. |
13 | OFFSET_REMOVAL_START_
MANUAL |
R/W | 0h | This bit initiates offset correction when OFFSET_REMOVAL_START_SEL is set to 0. |
12-9 | AUTO_OFFSET_REMOVAL_ACC_CYCLES | R/W | 0h | These bits define the number of samples required to generate an offset in auto offset correction mode |
8 | PAT_SELECT_IND | R/W | 0h | 0 = All LVDS output data lines have the same pattern, as determined by the PAT_MODES[2:0] bits
1 = Different test patterns can be sent on different LVDS data lines; see the LVDS Test Pattern Mode section for further details |
7 | PRBS_SYNC | R/W | 0h | 0 = Normal operation
1 = PRBS generator is in a reset state |
6 | PRBS_MODE | R/W | 0h | 0 = 23-bit PRBS generator
1 = 9-bit PRBS generator |
5 | PRBS_EN | R/W | 0h | 0 = PRBS sequence generation block disabled
1 = PRBS sequence generation block enabled; see the LVDS Test Pattern Mode section for further details |
4 | MSB_FIRST | R/W | 0h | 0 = The LSB is transmitted first on serialized output data
1 = The MSB is transmitted first on serialized output data |
3-2 | 0 | R/W | 0h | Must write 0 |
1-0 | ADC_RES | R/W | 0h | These bits control the ADC resolution.
00 = 12-bit resolution 01 = 14-bit resolution 11 = 10-bit resolution 10 = Unused |
