ZHCSIE4A June 2018 – July 2018 TMS320F28035-EP
PRODUCTION DATA.
The device contains an enhanced capture (eCAP) module. Figure 5-38 shows a functional block diagram of a module.
Figure 5-38 eCAP Functional Block Diagram The eCAP module is clocked at the SYSCLKOUT rate.
The clock enable bits (ECAP1 ENCLK) in the PCLKCR1 register turn off the eCAP module individually (for low-power operation). Upon reset, ECAP1ENCLK is set to low, indicating that the peripheral clock is off.
