R/W-0

LEGEND: R/W = Read/Write; R = Read only; -n = value after reset

Table 33-11. eQEP Unit Timer Register (QUTMR) Field Descriptions

Bits Name Description

31-0 QUTMR 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.
