Table8 is a summary showing the number of wait cycles and
hold cycles used for various address ranges.
Wait/Hold Summary Table

Table9 shows the recommended register settings for various
clock rates. Different clock rates require different register set-
tings because the flash program memories have specific set-
up and hold requirements that can be met only by using
enough wait cycles and hold cycles.
