Each EPWM module provides start of conversion events (PWM_SOCA and PWM_SOCB), that can be used to start conversion of external ADC module. In this device all PWM_SOCA and all PWM_SOCB events are ORed together and hence any of the EPWMs can initiate an ADC start of conversion. These events are then multiplexed with an PRU_ICSSG[0-1] host interrupts (ICSSG_x_HOST_INTn, where x = 0 to 1 and n = 1 or 2), allowing either PRU_ICSSG[0-1] or EPWM0 through EPWM8 modules to trigger the PWM_SOCA/PWM_SOCB event pins (EHRPWM_SOCA and EHRPWM_SOCB). The PWM_SOCA and PWM_SOCB event output signals are also routed back to the PRU_ICSSGx (where x = 0 to 1) modules as interrupts as shown in Figure 12-2231.
ICSSG_x_HOST_INTn (where x = 0 to 1 and n = 1 or 2) interrupts are mapped to Host-3 and Host-4 of the PRU_ICSSG Interrupt Controller.
