440GRx – PPC440GRx Embedded Processor
Table 21. I/O Specifications—PCI, UART, IIC, SPI, Ethernet, System and Debug Interfaces (Sheet 2 of 3)
Notes:
1. Ethernet interface meets timing requirements as defined by IEEE 802.3 standard.
2. SMIISync is a weak driver. Redrive SMIISync when driving more than one load.
3. TDO timing is referenced to the falling edge of TCK.
