QUTMR
R/W-0
LEGEND: R/W = Read/Write; R = Read only; -n = value after reset
Table 15-10. eQEP Unit Timer Register (QUTMR) Field Descriptions
Bits Name Value Description
31-0 QUTMR 0-FFFF FFFFh 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.

QUPRD
R/W-0
LEGEND: R/W = Read/Write; R = Read only; -n = value after reset
Table 15-11. eQEP Unit Period Register (QUPRD) Field Descriptions
Bits Name Value Description
31-0 QUPRD 0-FFFF FFFFh 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.
