在使用EQEP用于M/T方法测速时
If the QEPCTL[QCLM] bit is cleared, then the capture timer and capture period values are latched into the
QCTMRLAT and QCPRDLAT registers, respectively, when the CPU reads the position counter
(QPOSCNT).
If the QEPCTL[QCLM] bit is set, then the position counter, capture timer, and capture period values are
latched into the QPOSLAT, QCTMRLAT and QCPRDLAT registers, respectively, on unit time out.
根据数据手册给说明，将QEPCTL[QCLM]设置为0，在通过CPU连续读4次读取QPOSCNT的值，发现第三次读取的值，比别的3次数据值小于1，不知道怎么回事？请问说明原因导致的
