Proposed field range for configuration parameters
These are not intended to be restrictive, but to determine how many bits are needed to pass the parameter values from the software library driver into the firmware.
Name | Max value | Comments |
NW | 1024 | I think this is the current maximum |
P1 | 7 | Initial ped window length NP=2**P1 which would be 128 for P1=7 |
P2 | 7 | Local ped window length NP2=2**P2 which would be 128 for P2=7 |
IE | 1023 | for the CDC we need IE > NW-NP |
NPK | 15 | Lubomir is ok with max of 8; 15 uses the same # bits; can limit this to 8 in software |
H | 511 | Hit threshold |
TH | 511 | High timing threshold |
TL | 63 | Low timing threshold |
IBIT | 7 | Scaling factor for integral is 2**IBIT (using 4 for CDC & 7 uses same # bits) |
ABIT | 3 | Scaling factor for amplitude is 2**ABIT |
PBIT | 3 | Scaling factor for pedestal is 2**PBIT |
