PROM XC18V00 Data Sheet - Does the CF/pin need a pull-up when it is connected to a PROG?

Description

General Description: 

Why does the data sheet show a pull-up on the PROG pin of the FPGA? Don't all Xilinx FPGAs have a weak internal pull-up on the PROG pin?

解决方案

Yes, all Xilinx FPGAs have a weak internal pull-up on the PROG pin; however, it is recommended that a 4.7k pull-up be added externally.
