Master Clock Source

[bradp]

Firmware from 9/2/2010 has the new structure Sys.ClockSource which tells us which gate is making the master clock on PPmac. In the future this will be incorporated into the Task Manager, probably on the Tasks page as a permanent part of details window. It works as follows Sys.ClockSource retuns an integer which means the following: 63 to 48 -> Subtract 48 to get the Gate3 index of master 47 to 32 -> Subtract 32 to get the Gate2 index of master 19 to 4 -> Subtract 0 to get the Gate1 index of master returned value indicating problems: 0 -> No master -1 -> Multiple Masters found -4 to -19 -> ID chip setting and Gate1 clock source word do not agree. Number is the Gate1 index -32 to -47 -> ID chip setting and Gate2 clock source word do not agree. Number is the gate2 index -48 to -63 -> ID chip setting and Gate3 clock source word do not agree. Number is the Gate3 index
