Configure Components
  Each of the components you select establishes the basic register
  settings that implement the selected function. They also provide
  parameters and properties that allow you to tailor their precise
  configuration to your particular application. For example, a Pulse
  Width Modulator (PWM) User Module configures one or more
  digital PSoC blocks, one for each 8 bits of resolution. The user
  module parameters permit you to establish the pulse width and
  duty cycle. Configure the parameters and properties to
  correspond to your chosen application. Enter values directly or
  by selecting values from drop-down menus.
  Both the system-level drivers and chip-level user modules are
  documented in data sheets that are viewed directly in the PSoC
  Designer. These data sheets explain the internal operation of the
  component and provide performance specifications. Each data
  sheet describes the use of each user module parameter or driver
  property, and other information you may need to successfully
  implement your design.
