6.1 Event Manager (EV) Functional Blocks
All devices of the ’240x family, with the exception of the ’2402, have two event
managers, EVA and EVB. These two event managers are exactly identical to
each other in terms of functionality and register mapping/bit definition. For the
sake of brevity, only the functionality of EVA is explained. Minor differences
(such as naming conventions and register addresses) are highlighted as ap-
propriate.
Each EV module in the ’240x device contains the following functional blocks:
- Two general-purpose (GP) timers (described in section 6.3 on page 6-14).
- Three compare units (described in section 6.4 on page 6-37).
- Pulse-width modulation (PWM) circuits that include space vector PWM
circuits, dead-band generation units, and output logic (described in sec-
tion 6.5 on page 6-46, section 6.6 on page 6-55, and section 6.7 on
page 6-60).
- Three capture units (described in section 6.8 on page 6-66).
- Quadrature encoder pulse (QEP) circuit (described in section 6.9,
page 6-78).
- Interrupt logic (described in section 6.10 on page 6-82).
Figure 6–1 shows a block diagram of the EVA module and Figure 6–2 shows
a block diagram of the EVB module.
