POR Configuration Pull-up/down resistor value

my new board  use P1011 device and  for POR Configuration  i use 4.7K resistor  for pull-up/down not CPLD

i use that value   based on  P1020RDB schematic

P1020RDB use CPLD but  POR page has  pull-up/down resistors so i followed 

 

POR configuration Pins are connected with other ICs but those are high-impedance when hreset is asserted

 

but  sometimes POR configuration value is not set to Pull-up/down setting

if boot fail   i  checked  the values by codewarror

 

i wondoer  the resistor value is not correct , how do i  chose pull-up/down resistor ?

 

thank you in advance
