  * @brief
  * The rampSyringePump function handles the ramp-up for the syringe pump.
+ * This function calculates the new toggle time every 10 ms and updates FPGA
+ * with the new toggle.
+ * Motor speed is inversely proportional to the toggle time.
+ * Smaller the toggle time, faster the speed of the motor.
  * @details \b Inputs: syringePumpRampTimerCtr, syringePumpSetToggleTime
