15.4.2.4.2.2 Strobe Event Latch
The position-counter value is latched to the QPOSSLAT register on the rising edge of the strobe input by
clearing the QEPCTL[SEL] bit.
If the QEPCTL[SEL] bit is set, then the position counter value is latched to the QPOSSLAT register on the
rising edge of the strobe input for forward direction and on the falling edge of the strobe input for reverse
direction as shown in
.
The strobe event latch interrupt flag (QFLG[SEL]) is set when the position counter is latched to the
QPOSSLAT register.
