Hi, all
I read ti's application report about special usage of 28x eQEP modules. (spraah1, Using the eQEP Module in TMS320x280x, 28xxx as a Dedicated Capture)
and, I found some mistakes based on my supposition.
See below paragraph.
I think that underlined sentence is wrong.
Below is Edited paragraph.
The position counter is clocked by the QCLK. Therefore, two position counter counts would correspond to
an UPEVNT, when the QDECCTL:XCR bit is set to ‘0’. The position counter has to be configured to reset
on the maximum position using QEPCTL:PCRM bits. The QPOSMAX register should then be initialized to
a value that corresponds to two position counts i.e. one UPEVNT. A position counter overflow interrupt is
generated when the counter reaches its maximum count. The period value can then be read from the
capture period register in the interrupt service routine. When the QDECCTL:XCR bit is ‘1’ and only the
period measurement is required, QPOSMAX should be accordingly initialized to correspond to one
position count i.e. one UPEVNT.
Is it correct ?
