Time-Base (TB) Submodule
A time-base synchronization scheme connects all of the ePWM modules on a device. Each ePWM
module has a synchronization input (EPWMxSYNCI) and a synchronization output (EPWMxSYNCO). The
input synchronization for the first instance (ePWM1) comes from an external pin. The possible
synchronization connections for the remaining ePWM modules are shown in
Figure 2-4
,
Figure 2-5
, and
Figure 2-6
.
Scheme 1 shown in
Figure 2-4
applies to the 280x and 2801x devices. Scheme 1 also applies to the
2804x devices when the ePWM pinout is configured for 280x compatible mode (GPAMCFG[EPWMMODE]
= 0).
