    The 280x device contains up to four enhanced capture (eCAP) modules.
    Figure 4-5
    shows a functional
    block diagram of a module. See the
    TMS320x280x Enhanced Capture (eCAP) Module Reference Guide
    (literature number SPRU807) for more details.
    The eCAP modules are clocked at the SYSCLKOUT rate.
    The clock enable bits (ECAP1/2/3/4ENCLK) in the PCLKCR1 register are used to turn off the eCAP
    modules
    individually
    (for
    low
    power
    operation).
    ECAP3ENCLK, and ECAP4ENCLK are set to low, indicating that the peripheral clock is off.

    reset,
