Remarks 1.
The above figure shows the timing chart when both BFTE3 and BFTEN of the TMC0n register
are 1, and transfer from BFCMn3 to CM0n3, or from BFCMnx to CM0nx is enabled. Transfer is
not performed when BFTE3 = 0 or BFTEN = 0.

5.
To not use dead time, set the TM0CEDn bit of the TMC0n register to 1.
6.
The above figure shows an active-high case.
7.
INTCM01x is generated on a match between TM01 and CM01x (a and b in the above figure).
INTCM00x is not generated.
Figure 9-16 shows the overall operation image.
