Table 8 is a summary showing the number of access cycles
used for various address ranges.

Table 9 shows the recommended register settings for various
clock rates. Different clock rates require different register set-
tings because the flash EEPROM program memories have

specific setup and hold requirements that can be met only by
using enough wait cycles and hold cycles.
Between clock rates of 10 MHz and 20MHz, the number of
wait states required for memory access (either none or one)
depends on the desired power mode of the program memory.
