5.9.3 Enhanced Quadrature Encoder Pulse (eQEP)
The eQEP module interfaces directly with linear or rotary incremental encoders to obtain position,
direction, and speed information from rotating machines used in high-performance motion and position-
control systems.
Each eQEP peripheral comprises five major functional blocks:
• Quadrature Capture Unit (QCAP)
• Position Counter/Control Unit (PCCU)
• Quadrature Decoder Unit (QDU)
• Unit Time Base for speed and frequency measurement (UTIME)
• Watchdog timer for detecting stalls (QWDOG)
The eQEP peripherals are clocked by PERx.SYSCLK. Figure 5-52 shows the eQEP block diagram.
