Important: The value of a reserved bit must be maintained in software. When you modify registers containing reserved bit fields, you must use a read-modify-write operation to preserve state and prevent indeterminate system behavior.

misci Fields
Bit | Name | Description | Access | Reset |
---|---|---|---|---|
1 | bootFPGArdy | The value of the f2s_boot_from_fpga_ready signal from the FPGA fabric. If the FPGA is not in User Mode, the value of this field is undefined. 1 = FPGA fabric is ready to accept AXI master requests from the HPS2FPGA bridge. 0 = FPGA fabric is not ready (probably still processing a reset). |
RO | 0x0 |
0 | bootFPGAfail | The value of the f2s_boot_from_fpga_on_failure signal from the FPGA fabric. If the FPGA is not in User Mode, the value of this field is undefined. 1 = Boot ROM will boot from FPGA if boot from normal boot device fails. 0 = Boot ROM will not boot from FPGA if boot from normal boot device fails. |
RO | 0x0 |
