Peripheral Frame 2 only allows 16-bit accesses. All 32-bit accesses are ignored (invalid data can be returned or written).

The ePWM/HRPWM modules can be re-mapped to Peripheral Frame 3 where they can be accessed by the DMA module. To
achieve this, bit 0 (MAPEPWM) of MAPCNF register (address 0x702E) must be set to 1. This register is EALLOW protected.
When this bit is 0, the ePWM/HRPWM modules are mapped to Peripheral Frame 1.
