4.3 Enhanced PWM Modules
The 2833x/2823x devices contain up to six enhanced PWM (ePWM) modules (ePWM1, ePWM2, ePWM3,
ePWM4, ePWM5, ePWM6). Figure 4-4 shows the time-base counter synchronization scheme 3. Figure 4-
5 shows the signal interconnections with the ePWM.
Table 4-2 shows the complete ePWM register set per module and Table 4-3 shows the remapped register
configuration.

A. By default, ePWM and HRPWM registers are mapped to Peripheral Frame 1 (PF1). Table 4-2 shows this
configuration. To re-map the registers to Peripheral Frame 3 (PF3) to enable DMA access, bit 0 (MAPEPWM) of
MAPCNF register (address 0x702E) must be set to 1. Table 4-3 shows the remapped configuration.
