I have a question about the function SetTriggerSource in the class DRSBoard (DRS.h/DRS.cpp)
In the implementation there is the following comment:
// Set trigger configuration
// OR 0=CH1, 1=CH2, 2=CH3, 3=CH4, 4=EXT
// AND 8=CH1, 9=CH2, 10=CH3, 11=CH4, 12=EXT
What does this exactly mean? I am assuming that this are the bits which are set?
source = 1 ==> CH1
source = 4352 = 0x1100 ==> CH1 and ext
How is the AND/Or logic implemented?
When i have:
source = 0x1803 (bit 12,11,1,0)
what is the right way to set the brackets to expalin the logic?
(EXT and CH4 ) or CH2 or CH1 ?
