/// \unit
///
/// !Purpose
///
/// Interface for configuration the Periodic Interval Timer (PIT) peripheral.
///
/// !Usage
///
/// -# Initialize the PIT with the desired period using PIT_Init().
/// Alternatively, the Periodic Interval Value (PIV) can be configured
/// manually using PIT_SetPIV().
/// -# Start the PIT counting using PIT_Enable().
/// -# Enable & disable the PIT interrupt using PIT_EnableIT() and
/// PIT_DisableIT().
/// -# Retrieve the current status of the PIT using PIT_GetStatus().
/// -# To get the current value of the internal counter and the number of ticks
/// that have occurred, use either PIT_GetPIVR() or PIT_GetPIIR() depending
/// on whether you want the values to be cleared or not.
