Enhanced CAP Modules

The 2833x/2823x device contains up to six enhanced capture (eCAP) modules (eCAP1 to eCAP6). Figure 6-6 shows a functional block diagram of a module.

TMS320F28335 TMS320F28334 TMS320F28333 TMS320F28332 TMS320F28235 TMS320F28234 TMS320F28232 fbd_ecap_prs439.gifFigure 6-6 eCAP Functional Block Diagram

The eCAP modules are clocked at the SYSCLKOUT rate.

The clock enable bits (ECAP1ENCLK, ECAP2ENCLK, ECAP3ENCLK, ECAP4ENCLK, ECAP5ENCLK, ECAP6ENCLK) in the PCLKCR1 register are used to turn off the eCAP modules individually (for low power operation). Upon reset, ECAP1ENCLK, ECAP2ENCLK, ECAP3ENCLK, ECAP4ENCLK, ECAP5ENCLK, and ECAP6ENCLK are set to low, indicating that the peripheral clock is off.
