Bit | Field | Type | Reset | Description |
---|---|---|---|---|
15:14 | GPO0_SEL | RW | 00 | Selects the JESD SYNC_N signal coming out the GPO0
pin. Both bits can be asserted which does an oring of the SYNC_N
signals from each multi-DUC. bit 0 = 1 then multi-DUC1 SYNC_N used bit 1 = 1 then multi-DUC2 SYNC_N is used |
13:12 | SYNC0B_SEL | RW | 01 | Selects the JESD SYNC_N signal coming out the SYNC0B
pin. Both bits can be asserted which does an AND of the two SYNC_N
signals from each multi-DUC. bit 0 = 1 then multi-DUC1 SYNC_N used bit 1 = 1 then multi-DUC2 SYNC_N is used |
11:10 | SYNC1B_SEL | RW | 10 | Selects the JESD SYNC_N signal coming out the SYNC1B
pin. Both bits can be asserted which does an AND of the two SYNC_N
signals from each multi-DUC. bit 0 = 1 then multi-DUC1 SYNC_N used bit 1 = 1 then multi-DUC2 SYNC_N is used |
9:8 | GPO1_SEL | RW | 00 | Selects the JESD SYNC_N signal coming out the GPO1
pin. Both bits can be asserted which does an oring of the SYNC_N
signals from each multi-DUC. bit 0 = 1 then multi-DUC1 SYNC_N used bit 1 = 1 then multi-DUC2 SYNC_N is used |
7 | SPI4_ENA | RW | 0 | When set to a '1' the chip is in 4 pin SPI interface mode. |
6 | Reserved | RW | 0 | Reserved |
5:0 | ATEST | RW | 000000 | Select the analog test points: 000000: ATEST is off (ATEST Must be off during normal operation) 000001, 010001, 000110: VSSCLK 000010: VDDPLL1 000101: VDDCLK 000111, 001010, 010000: VDDAPLL18 001011: VDDAVCO18 001101: VDDS18 001110: VDDE1 001111, 111010, 111011, 111100: DGND 010011: VDDTX1 101001, 110001: AGND 101111, 111101, 111110, 11111: VDDDIG1 110000: VDDA18 |
