PIO, Timer, and DMA Signal Diagram
Note:
The timing values refer to minimum system timing requirements. Actual implementation requires
conformance to the specific protocol requirements. Refer to
Chapter 1
to identify the specific input and
output signals associated with the referenced internal controllers and supported communication protocols.
For example, FCC1 supports ATM/Utopia operation in slave mode, multi-PHY master direct polling
mode, and multi-PHY master multiplexed polling mode and each of these modes supports its own set of
signals; the direction (input or output) of some of the shared signal names depends on the selected mode.
