PRODUCTION DATA
The device contains an enhanced capture (eCAP) module. Figure 9-38 shows a functional block diagram of a module.
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.
