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.
signal names used.
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.
