CHAPTER 10 PWC (Pulse Width Count: Pulse Width Measurement)
●
Reactivation under operation
If a count operation is restarted after it was started, the followings may occur depending on the timing.
• In the pulse width single count mode, if starting a measurement end edge is simultaneously
The operation is restarted and waits for a measurement start edge, but a measurement end flag (EDIR) is
set.
• In the pulse width continuous measurement mode, if starting a measurement end edge is simultaneously
The operation is restarted and waits for a measurement start edge, but the measurement end flag (EDIR)
is set. The measurement result at that point is transferred to the PWCR.
When restarting an operation in progress, interrupt control or others must be performed with care to the
operation of flags, as mentioned above.
