Bit | Field | Type | Reset | Description |
---|---|---|---|---|
7 | LSB1_HR_FLAG_EN | R/W | 0h | This bit enables the HiRes flag on LSB1. 0 : LSB1 is stuck to 0 1 : LSB1 carries the high-resolution flag |
6 | LSB0_HR_FLAG_EN | R/W | 0h | This bit enables the HiRes flag on LSB0. 0 : LSB0 is stuck to 0 1 : LSB0 carries the high-resolution flag |
5 | LOAD_RES | R/W | 0h | This bit enables loading of high- or low-resolution values. 0 : High- and low-resolution values are not updated 1 : High- and low-resolution values are updated |
4 | TRIG_SEL_AB_CD | R/W | 0h | This bit determines if the TRIGAB or TRIGCD pin is used for burst mode; must be configured individually for channel AB and channel CD with paging. 0 : Uses the TRIGAB, TRIGCD pin separately 1 : Uses the TRIGCD pin when set for the SerDes AB SPI; uses the TRIGAB pin when set for the SerDes CD SPI |
3 | AUTO_TRIG_EN | R/W | 0h | This bit enables an automatic trigger in burst mode (ignores the TRIGAB, TRIGCD inputs). 0 : Disable auto trigger; trigger is accepted from the pin 1 : Enable auto trigger; pin trigger is ignored |
2 | 0 | R/W | 0h | Must read or write 0 |
1 | RATIO_INVALID | R | 0h | This bit generates an alarm flag when the duty cycle ratio between the high- and low-resolution counter is set incorrectly. 0 : LowRes, HighRes ratio is valid (≥ 3) 1 : LowRes, HighRes ratio is valid (< 3) |
0 | 0 | R/W | 0h | Must read or write 0 |
