Information

Note
The polarity control must be used only in Combine mode.
35.4.18 Initialization
The initialization forces the CHnOI bit value to the channel (n) output when a one is
written to the INIT bit.
The initialization depends on COMP and DTEN bits. The following table shows the
values that channels (n) and (n+1) are forced by initialization when the COMP and
DTEN bits are zero.
Table 35-189. Initialization behavior when (COMP = 0 and DTEN = 0)
CH(n)OI CH(n+1)OI Channel (n) Output Channel (n+1) Output
0 0 is forced to zero is forced to zero
0 1 is forced to zero is forced to one
1 0 is forced to one is forced to zero
1 1 is forced to one is forced to one
The following table shows the values that channels (n) and (n+1) are forced by
initialization when (COMP = 1) or (DTEN = 1).
Table 35-190. Initialization behavior when (COMP = 1 or DTEN = 1)
CH(n)OI CH(n+1)OI Channel (n) Output Channel (n+1) Output
0 X is forced to zero is forced to one
1 X is forced to one is forced to zero
Note
The initialization feature must be used only in Combine mode
and with disabled FTM counter. See the description of the ../dil/
FTM.xml#ftm_sc_clks field in the Status and Control register.
35.4.19 Features priority
The following figure shows the priority of the features used at the generation of channels
(n) and (n+1) outputs signals.
