Max. 6 points
1 phase Range: -2,147,483,648 to 
+2,147,483,647 counts
General rule: Select counter 
combinations with a combined 
counting frequency of 60kHz or less.
Note; 
all counters are latched (EEPROM 
backed-up)
If high speed counter is used with the 
HSCS or HSCR instruction, a 
combined counting frequency of 
30kHz or less.
