NOTES:
– CNTIN = 0x0010
– Channel (n) is in low-true combine mode with CNTIN < C(n)V < C(n+1)V < MOD
– C(n)V = 0x0015

Figure 39-98. FTM behavior after reset when the channel (n) is in Combine mode
The following figure shows an example when the channel (n) is in Output Compare mode
and the channel (n) output is toggled when there is a match. In the Output Compare
mode, the channel output is not updated to its initial value when there is a write to CNT
register (item 3). In this case, use the software output control (Software output control) or
the initialization (Initialization) to update the channel output to the selected value (item
4).
