Details

When using any timer instance in capture mode, starting the timer using a zero (ZCOND) or load (LCOND) condition causes the timer to capture the zero or load value instead of the captured value in the respective TIMx.CC register. This affects periodic use cases such as period and pulse width capture.

Workaround

Use the below software flow to calculate the period or pulse width. See the timx_timer_mode_capture_duty_and_period in the MSPM0-SDK for an example of the workaround.

• Disable ZCOND or LCOND by setting to 0h.
• When a capture occurs, the capture value is correctly captured in TIMx.CC
• Restart the timer by setting TIMx.CTR to the reload value (load or 0)
