Clock Signals
The processor can use an external clock or a crystal. Refer to the
CLKIN pin description in
tion program can configure the processor to use its internal
clock generator by connecting the necessary components to the
CLKIN and XTAL pins.
tions used for a fundamental frequency crystal operating in
parallel mode.
Note that the clock rate is achieved using a 16.67 MHz crystal
and a PLL multiplier ratio 16:1. (CCLK:CLKIN achieves a clock
speed of 266.72 MHz.) To achieve the full core clock rate, pro-
grams need to configure the multiplier bits in the
PMCTL register.

Applies only for CLK_CFG1–0 = 00 and default values for PLL control bits in the PMCTL register.
Any changes to PLL control bits in the PMCTL register must meet core clock timing specification t

Actual input jitter should be combined with AC specifications for accurate timing analysis.
Jitter specification is maximum peak-to-peak time interval error (TIE) jitter.
