"14.0 QUADRATURE ENCODER INTERFACE (QEI) MODULE
This section describes the Quadrature Encoder Interface (QEI) module and associated operational modes. The QEI module provides the interface to incremental encoders for obtaining mechanical position data.

The operational features of the QEI include:
• Three input channels for two phase signals and **index pulse**
• 16-bit up/down position counter
• Count direction status
• Position Measurement (x2 and x4) mode
• Programmable digital noise filters on inputs
• Alternate 16-bit Timer/Counter mode
• Quadrature Encoder Interface interrupts
These operating modes are determined by setting the appropriate bits QEIM (QEICON).
Figure 14-1 depicts the Quadrature Encoder Interface block diagram.
