9.8.4 USB UDCA Head register (USBUDCAH - 0xFFE0 C280)
9.8.5 USB EP DMA Status register (USBEpDMASt - 0xFFE0 C284)
Software can also use this register to initiate a DMA transfer to proactively fill an IN
endpoint buffer before an IN token packet is received from the host.
USBDMARSet is a write only register.
The USBDMARSet bit allocation is identical to the USBDMARSt register
Table 331. USB DMA Request Set register (USBDMARSet - address 0xFFE0 C258) bit
The UDCA (USB Device Communication Area) Head register maintains the address
where the UDCA is located in the USB RAM. Refer to
communication area”
UDCA and DMA descriptors. USBUDCAH is a read/write register.
Bits in this register indicate whether DMA operation is enabled for the corresponding
endpoint. A DMA transfer for an endpoint can start only if the corresponding bit is set in
this register. USBEpDMASt is a read only register.
