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.

imgcfg_ctrl_00 Fields

Bit Name Description Access Reset
24 s2f_condone_oe 
This bit has an effect on CSS/PIN only if curresponding override is enabled.
1: Drive CONF_DONE pin to 0.
0: Disable CONF_DONE pin drive from HPS, and allow default pull-up to take over.

HPS can drive CONF_DONE pin 0 to delay the FPGA from entering user mode.
RW 0x0
16 s2f_nstatus_oe 
This bit has an effect on CSS only if curresponding override is enabled.
1: Drive nSTATUS pin to 0.
0: Disable nSTATUS pin drive from HPS, and allow default pull-up to take over.

Driving this pin has no effect on CSS once the FPGA is in user mode.
HPS can drive this pin 0 to delay the initialization phase of CSS.
During configuation phase, HPS can drive this pin 0 to end the current configuration and initialize a reconfiguration.
RW 0x0
8 s2f_nconfig 
This bit has an effect on CSS only if curresponding override is enabled.
1: Drive nCONFIG input to CSS 1.
0: Drive nCONFIG input to CSS 0

The nCONFIG input is used to put the FPGA into its reset phase. If the FPGA was configured, its operation stops and it will have to be configured again to start operation.
