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鈥檚 and EVB鈥檚 timers, compare units, and capture units function
identically. However, timer/unit names differ for EVA and EVB. Table 51 shows the module and signal names
used. Table 51 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鈥攈owever,
module/signal names would differ.
