9500 datasheet - What is the "block software selectable" option for pullup resistors?
Record #5921
Product Family: Hardware Urgency: Standard General Description: The footnote in the datasheet reads: "Pull-up resistors are used to prevent floating pins during programming and other times. They are disabled during normal operations. They may be enabled/disabled in block software selectable." So what is this block software selectable option? Solution 1: This is a misprint in the databook. There is no block selectable option in the CPLD solution. This documentation error exists in version 3 and 4 of the 9500 datasheet.
