• 4-event time-stamp registers (each 32 bits).
• Interrupt on either of the four events.

SysConfig Features

Note

It is strongly recommend to use SysConfig where it is available instead of using direct SW API calls. This will help simplify the SW application and also catch common mistakes early in the development cycle.

• Support for ECAP instance selection.
• Specifying the behaviour of Time-Stamp counter during an emulation event.
• Support for ECAP modes - APWM or Capture mode.
• Support for event polarity in capture mode.
• Interrupt source configuration.
• Support for APWM polarity, period and compare values in APWM mode.
