CPERiod
CPERiod command/query
The CPERiod command allows you to set the state analyzer for input
clock periods of greater than or less than 60
11s.
Either LT or GT can be
specified. LT signifies a state input clock period of less than 60 ns, and
GT signifies a period of greater than 60 ns.
Because count tagging requires a
minimum clock period of 60 ns, the
CPERiod and TAG commands are interrelated (the TAG command is in
the STRace subsystem).
When
the clock period is set to Less Than, count
tagging is turned off. When count tagging is set to either state or time, the
clock period is automatically set to Greater Than.
The CPERiod query returns the current setting of clock period.
