Description

Device OUT Endpoint 15 Buffer Address Register

Register Layout

Bits Access Reset Description
[31:0] R Unknown ALT_USB_DEV_DOEPDMAB15_DOEPDMAB15

Field : doepdmab15

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_DEV_DOEPDMAB15_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.
