EVA and EVB timers, compare units, and capture units function identically. However, timer/unit names differ for EVA and EVB. Table 7 shows the module and signal names used. Table 7 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 7.
