The VCO frequency is divided by a factor which is defined by the output divider
(pll_set_divout). Of course only a limited accuracy of the output frequencies can be
achieved by this approach.Table 233 and Table 234: Shows the accuracy achieved for
various frequencies (integer multiples of 1 MHz and some typical RS232 frequencies) and
the divider ratios to be used. The register bit ClkOutEn enables the clock at CLKOUT pin.
The following formula can be used to calculate the output frequency:
fout = 13.56 MHz pll_set_divb /pll_set_divout
Remark: At the value 0 to 7 have special division values.
The following Table 235 shows the recommended divider values for typical clock
frequencies.
Remark: The recommended value for pll_set_divb = 00h (divider value = 23). In this case
the internal current consumption of the IntegerN PLL is a minimum.
