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.
2. n = 0, 1
3. x = 4, 5
4. INTCM0nx is generated on a match between TM0n and CM0nx (a and b in the above figure).
Figure 9-16 shows the overall operation image.
