Notes:

Reserved signals should be disconnected for compatibility with future revisions of the device. Non-user signals are reserved

for manufacturing and test purposes only. The assigned signal name is used to indicate whether the signal must be

unconnected (Reserved), pulled down (VSS), or pulled up (VDD).

Signal function during power-on reset is determined by the RCW source type.

Selection of TDM versus RGMII functionality is determined by the RCW bit values.

Selection of RapidIO, SGMII, and PCI Express functionality is determined by the RCW bit values.

Selection of the GPIO function and other functions is done by GPIO register setup. For configuration details, see the GPIO

chapter in the MSC8252 Reference Manual.

Open-drain signal.

Internal 20 K

Ω pull-up resistor.

For signals with GPIO functionality, the open-drain and internal 20 K

Ω pull-up resistor can be configured by GPIO register

programming. See the GPIO chapter of the MSC8252 Reference Manual for configuration details.

Connect to power supply via external filter. See Section 3.2, PLL Power Supply Design Considerations for details.

10. Pin types are: Ground = all VSS connections; Power = all VDD connections; I = Input; O = Output; I/O = Input/Output; NC =

not connected.
