1) The CLKOUT cycle time is influenced by PLL jitter. For longer periods the relative deviation decreases (see

PLL deviation formula).

Figure 23 CLKOUT Signal Timing

Note: The term CLKOUT refers to the reference clock output signal which is generated

by selecting fSYS as the source signal for the clock output signal EXTCLK on pin

P2.8 and by enabling the high-speed clock driver on this pin.
