C28 Enhanced QEP (eQEP) Module
Description
The position-counter value is latched into this register on strobe event as defined by the
QEPCTL[SEL] bits.
Figure 9-31. eQEP Position Counter Latch (QPOSLAT) Register
Description
The position-counter value is latched into this register on unit time out event.
Figure 9-32. eQEP Unit Timer (QUTMR) Register
Description
This register acts as time base for unit time event generation. When this timer value matches
with unit time period value, unit time event is generated.
Figure 9-33. eQEP Register Unit Period (QUPRD) Register
Description
This register contains the period count for unit timer to generate periodic unit time events to latch
the eQEP position information at periodic interval and optionally to generate interrupt. Writes to
this register should always be full 32-bit writes.
