External Bus Timing
The following parameters specify the behavior of the XC238xC bus interface.
Note: These parameters are not subject to production test but verified by design and/or
characterization.
Note: Operating Conditions apply.

CLKOUT Signal Timing
Note: The term CLKOUT refers to the reference clock output signal which is generated
by selecting
f
SYS 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.
