Register : grxfsiz

Description

Receive FIFO Size Register

Register Layout

Bits Access Reset Description
[13:0] RW 0x2000 ALT_USB_GLOB_GRXFSIZ_RXFDEP
[31:14] ??? 0x0 UNDEFINED

Field : rxfdep

Mode: Host and Device

RxFIFO Depth (RxFDep)

This value is in terms of 32-bit words.

Minimum value is 16

Maximum value is 32,768

The power-on reset value of this register is specified as the

Largest Rx Data FIFO Depth during configuration. If Enable Dynamic FIFO Sizing was selected,

you can write a new value in this field. Programmed values must not exceed the power-on value

Data Structure Documentation

struct ALT_USB_GLOB_GRXFSIZ_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.
