 they count the number of pulses, and thus, allow you to keep track of time.
 
 A timer is effectively configured to run at a given frequency, and it will count. It will either count to its maximum
-limit (unsigned 32-bit integer's maximum value for STM32s), or until it reaches a configured N<sub>period</sub> value.
+limit (either unsigned 32-bit or 16-bit integer's maximum value for STM32s), or until it reaches a configured N<sub>period</sub> value.
 Once that value is reached, usually, the timer is reset and it will either stop or restart, depending on the configuration.
 The functionality of a generic timer is illustrated in the figure below.

 ## The Mode Input
 
 The mode input determines which control mode the driver uses. Since we use the phase-enabled mode, we need to pull the pin high.
-Do this by connecting the MODE input through a resistor (say 5 kOhm one) to the 3.3 V output of the STM32 Nucleo board.
