Note
Maximum internal requirements for clocks derived from CLKI must be considered 
when determining the frequency of CLKI. See Section 6.1.2, “Internal Clocks” on page 
43 for
 internal clock requirements.
Note
Maximum internal requirements for clocks derived from CLKI2 must be considered 
when determining the frequency of CLKI2. See Section 6.1.2, “Internal Clocks” on page 
43 for
 internal clock requirements.
