Pin Assignments

MPC5121E/MPC5123 Data Sheet, Rev. 4

Freescale Semiconductor

1) This pin is an input or open-drain output. This pin can not be configured. There is an internal pull-up resistor implemented.

2) This pin is an input only. This pin can not be configured.

3) These JTAG pins have internal pull-up P-FETs. This pin can not be configured.

4) This pins should have an external pull-up resistor. Follow PCI specification and see System Design Information.

5) This test pin must be tied to VSS.

6) This pin contains an enabled internal Schmitt trigger.

NOTE

This table indicates only the pins with permananently enabled internal pull-up, pull-down,

or Schmitt trigger. Most of the digital I/O pins can be configured to enable internal pull-up,

pull-down, or Schmitt trigger. See the MPC5121e Microcontroller Reference Manual, IO

Control chapter.
