System Design Information
the large value of the pull-up/pull-down resistor should minimize the disruption of signal quality or speed
for the output pins.
21.7
Pull-Up Resistor Requirements
The MPC8347E requires high resistance pull-up resistors (10 kΩ is recommended) on open-drain pins,
2
including I
C pins, the Ethernet Management MDIO pin, and IPIC interrupt pins.
For more information on required pull-up resistors and the connections required for the JTAG interface,
refer to application note AN2931, PowerQUICC™ Design Checklist.
