Direct Drive
When direct drive is configured (CLKCFG = 011
disabled and the CPU clock is directly driven from the internal oscillator with the input
clock signal.

The timings listed below that refer to TCLs therefore must be calculated using the
minimum TCL that is possible under the respective circumstances. This minimum value
can be calculated via the following formula:
For two consecutive TCLs the deviation caused by the duty cycle of

require an even number of TCLs (2, 4, …) may use the formula 2TCL = 1/
