6.5.5 Control for ADC Event Trigger Signal Generation from ePWMx Modules
This microcontroller implements 7 ePWM modules, see Figure 6-4. Each of these modules generate two
outputs, SOCA (Start Of Conversion) and SOCB, for use in triggering the on-chip ADC modules. Registers
from the I/O multiplexing module are used to control the logic for generation of the ePWM_A1, ePWM_A2,
ePWM_AB, and ePWM_B signals from these ePWMx_SOCA and ePWMx_SOCB signals.
