6.3.18 Timer characteristics
TIM timer characteristics
The parameters given in the Table 61 are guaranteed by design.
Refer to Section 6.3.13: I/O port characteristics for details on the input/output alternate
function characteristics (output compare, input capture, external clock, PWM output).

1. Guaranteed by characterization results, not tested in production.
2. The delay is characterized for 100 mV input step with 10 mV overdrive on the inverting input, the non-
inverting input set to the reference.
3. In TSSOP14 package, where V
DDA
pin is shared with V
DD
pin, I/O toggling should be minimized to reach
the values given in the above table. I/O toggling with loaded I/O pins can generate ripple on V

and
degrade the comparator performance.
4. Comparator consumption only. Internal reference voltage (necessary for comparator operation) is not
included.
