7.5.5 AHB to APBX DMA Device Assignment Register
This register allows reassignment of the APBX device connected to the DMA Channels.
HW_APBX_DEVSEL: 0x040
HW_APBX_DEVSEL_SET: 0x044
HW_APBX_DEVSEL_CLR: 0x048
HW_APBX_DEVSEL_TOG: 0x04C
In this chip, apbxdma channel resource is enough for peripherals, so this register is of no
use and reserved.
