User manual
9.8.6 USB EP DMA Enable register (USBEpDMAEn - 0xFFE0 C288)
9.8.7 USB EP DMA Disable register (USBEpDMADis - 0xFFE0 C28C)
9.8.8 USB DMA Interrupt Status register (USBDMAIntSt - 0xFFE0 C290)
Writing one to a bit to this register will enable the DMA operation for the corresponding
endpoint. Writing zero has no effect.The DMA cannot be enabled for control endpoints
EP0 and EP1. USBEpDMAEn is a write only register.
Table 334. USB EP DMA Enable register (USBEpDMAEn - address 0xFFE0 C288) bit
Writing a one to a bit in this register clears the corresponding bit in USBEpDMASt. Writing
zero has no effect on the corresponding bit of USBEpDMASt. Any write to this register
clears the internal DMA_PROCEED flag. Refer to
descriptor fetch”
progress for an endpoint when its corresponding bit is cleared, the transfer is completed
before the DMA is disabled. When an error condition is detected during a DMA transfer,
the corresponding bit is cleared by hardware. USBEpDMADis is a write only register.
Table 335. USB EP DMA Disable register (USBEpDMADis - address 0xFFE0 C28C) bit
Each bit of this register reflects whether any of the 32 bits in the corresponding interrupt
status register are set. USBDMAIntSt is a read only register.
