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 frequency of

f
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:
TCL
For two consecutive TCLs the deviation caused by the duty cycle of
so the duration of 2TCL is always 1/
used only once for timings that require an odd number of TCLs (1, 3, …). Timings that
require an even number of TCLs (2, 4, …) may use the formula 2TCL = 1/
