Integrated I/O (IIO) Configuration Registers
14.2.124 XPPMEVH[0:1]
XP PM Events High
Selections in this register correspond to fields within the PEX packet header. Each field 
selection is ANDed with all other fields in this register including the XPPMEVL except for 
the Global Event signals. These signals are OR’ed with any event in the XPPMEVL and 
enables for debug operations requiring the accumulation of specific debug signals.The 
qualifications for fields in this register are as follows:

global_event_selection:
Global Event Selection  
Selects which GE[3:0] is used for event counting. This field is OR’d with other 
fields in this register. The GEs cannot be qualified with other PerfMon signals.If 
more than 1 GE is selected then the resultant event is the OR between each GE.
However, properly counting Global Event based on design, XP PM Response 
Control Register bit [13:11] CENS must be set to choose GE[3:0] and also 
bit[18:17] CNTEVSEL must be set to 2’b10.
