The Stratix® IV and HardCopy® IV Device Pin Connection Guideline documents state that the following dual-purpose pins are influenced by nIO_PULLUP :
nCSO, ASDO, DATA[7..0], CLKUSR, INIT_DONE, DEV_OE, DEV_CLRn
This list is incorrect. nCSO and ASDO are not dual-purpose and should not be listed, and the CRC_ERROR pin is missing from the list.
The correct list of dual-purpose pins which are influenced by the nIO_PULLUP pin in Stratix IV and HardCopy IV devices are :
CLKUSR, DATA[7:0], INIT_DONE, DEV_OE, DEV_CLRn and CRC_ERROR
