Preliminary
in
This chapter describes the Quadrature Encoder Inter-
face (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 module include:
• 32-bit position counter
• 32-bit Index pulse counter
• 32-bit Interval timer
• 16-bit velocity counter
• 32-bit Position Initialization/Capture/Compare
• 32-bit Position Compare Low register
• 4X Quadrature Count mode
• External Up/Down Count mode
• External Gated Count mode
• External Gated Timer mode
• Internal Timer mode
