1)tms320c6713b晶片手冊48頁中有一段備注：
‡ IPD = Internal pulldown, IPU = Internal pullup. [To oppose the supply rail on these IPD/IPU signal pins, use external pullup or pulldown resistors no greater than 4.4 kΩ and 2.0 kΩ, respectively.]
請問To oppose the supply rail on these IPD/IPU signal pins具體什麼意思？是防止電源幹擾的意思嗎？
2)‡ IPD = Internal pulldown, IPU = Internal pullup. [To oppose the supply rail on these IPD/IPU signal pins, use external pullup or pulldown resistors no greater than 4.4 kΩ and 2.0 kΩ, respectively.]
§ To ensure a proper logic level during reset when these pins are both routed out and 3−stated or not driven, it is recommended to include an external 10 kΩ pullup/pulldown resistor to sustain the IPU/IPD, respectively.
上面兩段話中我了解意思是一個要求上下拉電阻應不大于4.4 kΩ和2.0 kΩ，另一段要求上下拉電阻應為10 kΩ，這兩段話是否互相沖突？
請各位專家幫忙解答下，非常感謝！
