For power-up sequencing, power-up reset, and normal reset
(hot reset) timing requirements, refer to Table 26 and Figure 13,
respectively.

1 CCLK is the internal processor clock or instruction cycle time. The period of this clock is equal to the system clock period (tSCLK) divided by the system clock ratio
(SCLKRAT2–0). For information on available part numbers for different internal processor clock rates, see the Ordering Guide on Page 45.

1 For more information, see Table 3 on Page 12.
3 LCLK_P and SCLK_P must be connected to the same source.
4 The value of (tLCLK / LCLKRAT2-0) must not violate the specification for tCCLK.
5 Actual input jitter should be combined with ac specifications for accurate timing analysis.
6 Jitter specification is maximum peak-to-peak time interval error (TIE) jitter.
