AR# 5921

9500 datasheet - What is the "block software selectable" option for pullup resistors?

Description

Keywords: 9500, datasheet, pullup

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

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.
