The operational features of the QEI include the follow-
ing:
• Three input channels for two phase signals and
• 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
The QEI module’s operating mode is determined by
setting
(QEICON<10:8>). Figure 17-1 depicts the Quadrature
Encoder Interface block diagram.
