440EP – PPC440EP Embedded Processor
Data Sheet
Table 19. I/O Specifications—PCI, USB, UART, IIC, SPI, Ethernet, System and Debug Interfaces (Sheet 1 of 3)
Notes:
1. Ethernet interface meets timing requirements as defined by IEEE 802.3 standard.
2. EMCSync is a weak driver. Redrive EMCSync when driving more than one load.
