Used to send configuration image to FPGA.
The DATA register accepts 4 bytes of the configuration image on each write. The configuration image byte-stream is converted into a 4-byte word with little- endian ordering. If the configuration image is not an integer multiple of 4 bytes, software should pad the configuration image with extra zero bytes to make it an integer multiple of 4 bytes.
The FPGA Manager converts the DATA to 16 bits wide when writing CB.DATA for partial reconfiguration.
The FPGA Manager waits to transmit the data to the CB until the FPGA is able to receive it. For a full configuration, the FPGA Manager waits until the FPGA exits the Reset Phase and enters the Configuration Phase. For a partial reconfiguration, the FPGA Manager waits until the CB.PR_READY signal indicates that the FPGA is ready.

Field : Write Data Value - value | |
Accepts configuration image to be sent to CB when the HPS configures the FPGA. Software normally just writes this register. If software reads this register, it returns the value 0 and replies with an AXI SLVERR error. 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.
