General PCB design guidelines
Power supply decoupling should be performed as shown in Figure 9: Power supply scheme.
The 10 nF capacitor should be ceramic (good quality) and it should be placed as close as
possible to the chip.
6.3.17 Temperature sensor characteristics
6.3.18 Timer characteristics
The parameters given in the following tables are guaranteed by design.
Refer to Section 6.3.14: I/O port characteristics for details on the input/output alternate
function characteristics (output compare, input capture, external clock, PWM output).
