==PL initialization signals ==
This page provides information about the Programmable Logic (PL) initialization signals: PROGRAM_B, INIT_B, and DONE.
* DONE has no pull-up/down. It does not require any external pull-up or pull-down but can be used for connecting a user led for a configuration completed indication (see for example [https://mirror.dave.eu/bora/hw/BoraXEVB/S-EVBBX0000C0R-1.6.1_color.pdf#page=4 BoraXEVB schematics]).
=== External pull-ups ===* PROGRAM_B: for UG-585 indicates to use a stronger 4.7kΩ pull-upresistor for this signal. This value was not known when the Xilinx Zynq 7000 family was released. Nevertheless, to date, as indicated in the UGno issues have been reported although this pull-585up is a little bit weaker. In any case, place an external pull-up to a 3.3V controlled power domain in order to can be put it in parallel with the internal 10kΩ resistor to get a stronger pull-up. For more details, please contact [mailto:helpdesk@dave.eu the technical support].
* INIT_B: for using this signal as ''PL initializing signal Low-to-High transition'', place an external pull-up to a 3.3V controlled power domain.
