Register : hcdmab11

Description

Host Channel 11 DMA Buffer Address Register

Register Layout

Bits Access Reset Description
[31:0] RW 0x0 ALT_USB_HOST_HCDMAB11_HCDMAB11

Field : hcdmab11

Holds the current buffer address.

This register is updated as and when the data transfer for the corresponding end point

is in progress. This register is present only in Scatter/Gather DMA mode. Otherwise this

field is reserved.

struct ALT_USB_HOST_HCDMAB11_s

WARNING: The C register and register group struct declarations are provided for convenience and illustrative purposes. They should, however, be used with caution as the C language standard provides no guarantees about the alignment or atomicity of device memory accesses. The recommended practice for writing hardware drivers is to use the SoCAL access macros and alt_read_word() and alt_write_word() functions.
