1 - BPM encoded Clock/Command sent to DORIC but with Bypass outputs
on DORIC active. Clock/Command from DORIC are
then fedback into the Redundant inputs of the module. Data readout is from
the Master ABCD(s) directly.
2 – Clock/Command is fed directly into the Redundant inputs of module. Data readout is from Master ABCD(s) directly.
3 - BPM encoded Clock/Command to DORIC, but BPM+ is not active, data readout from VDC.
4
- BPM encoded Clock/Command to DORIC, but BPM- is not active, data readout
from VDC.
If Select is set to 0 CLK1 and COM1 are used for data transmission to the
support card.
If Select is set to 1 CLK0 and COM0 are used for data transmission to the
support card.
Command format takes the form of ABCD Slow Commands, <1010111><WXYZ><DATAX>,
where:
| W | X | Y | Z | Mode |
| 0 | 0 | 0 | 0 | 0 |
| 0 | 0 | 0 | 1 | 1 |
| 0 | 0 | 1 | 0 | 2 |
| 0 | 0 | 1 | 1 | 3 |
| 0 | 1 | 0 | 0 | 4 |
| 0 | 1 | 0 | 1 | DATA0 |
| 0 | 1 | 1 | 0 | DATA1 |
| 0 | 1 | 1 | 1 | DATA2 |
| 1 | 0 | 0 | 0 | DATA3 |
| 1 | 0 | 0 | 1 | DATA4 |
| 1 | 0 | 1 | 0 | DATA5 |
Modes 0-4 represents the 5 Readout modes.
DATA 0-5 allow the software configuration of the VDC data receiver DACs and the DORIC drive outputs:
DATA0 - Configure VDC0 DAC (16-Bit Register)
DATA1 - Configure VDC1 DAC (16-Bit Register)
DATA2 - Set DORIC BPM Drive current to 60uA
