Description

This register contains the logical endpoint direction(s).

Register Layout

Bits Access Reset Description
[31:0] R 0x0 Endpoint Direction

Field : Endpoint Direction - ghwcfg1

This 32-bit field uses two bits per endpoint to determine the endpoint direction.

Endpoint

  • Bits [31:30]: Endpoint 15 direction
  • Bits [29:28]: Endpoint 14 direction

...

  • Bits [3:2]: Endpoint 1 direction
  • Bits[1:0]: Endpoint 0 direction (always BIDIR)

struct ALT_USB_GLOB_GHWCFG1_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.
