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 Field Access Macros: | |

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.
