Event Manager Modules (EVA, EVB)
The event-manager modules include general-purpose (GP) timers, full-compare/PWM units, capture units,
and quadrature-encoder pulse (QEP) circuits. EVA and EVB timers, compare units, and capture units function
identically. However, timer/unit names differ for EVA and EVB. Table 4−2 shows the module and signal names
used. Table 4−2 shows the features and functionality available for the event-manager modules and highlights
EVA nomenclature.
Event managers A and B have identical peripheral register sets with EVA starting at 7400h and EVB starting
at 7500h. The paragraphs in this section describe the function of GP timers, compare units, capture units, and
QEPs using EVA nomenclature. These paragraphs are applicable to EVB with regard to function—however,
module/signal names would differ. Table 4−3 lists the EVA registers. For more information, see the
TMS320x281x DSP Event Manager (EV) Reference Guide (literature number SPRU065).
