IO_Cfg_Write_event  =  (REQCMP[0] & CMPR[1] & RDWR[1] & DATALEN & (TTYP[2] + 
(TTYP[1] & CFGTYP)))   
IO_Cfg_Read_event  =  (REQCMP[0] & CMPR[1] & RDWR[0] & DATALEN & (TTYP[2] + 
(FMTTYP[1] & CFGTYP))) 
Mem_Write_event =  (REQCMP[0] & CMPR[0] & RDWR[1] & DATALEN & TTYP[3] & 
LOCK & EXTADDR & SNATTR) 
Note: An outbound memory write does not have a snoop attribute as an inbound 
memory write has. So the user should set SNATTR=”11” for outbound memory write 
transaction event counting.
Mem_Read_event =  (REQCMP[0] & CMPR[1] & RDWR[0] & DATALEN & (( TTYP[3] & 
LOCK & EXTADDR & SNATTR) + TTYP[2] + (TTYP[1] & CFGTYP)))
Note: For outbound memory reads there is no concept of issuing a snoop cycle. The 
user should select SNATTR=“11” for either snoop attribute.
Msg_event = (TTYP[0] & DND)
(INOUTBND[0] & (MatchEq) + (IOBND[1] & (MatchEq) 
Setting both bits in INOUTBND is acceptable however the performance data 
gathered will not be accurate since once one header can be counted at a time
