PERIPHERALS
The integrated peripherals of the TMS320x240xA are described in the following subsections:
Two event-manager modules (EVA, EVB)
Enhanced analog-to-digital converter (ADC) module
Controller area network (CAN) module
Serial communications interface (SCI) module
Serial peripheral interface (SPI) module
PLL-based clock module
Digital I/O and shared pin functions
External memory interfaces (LF2407A only)
Watchdog (WD) timer module
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 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.
