The MCF5272 features the same FEC as the MPC860T with a few differences. The following list pertains
to the MCF5272.
Freescale Semiconductor
•
•
•
•
•
Limited throughput full-duplex 100 Mbps operation. External bus use is the limiting factor.
Only big-endian mode is supported for buffer descriptors and buffers.
Separate interrupt vectors for Rx, Tx and non-time critical interrupts
Interrupt priority is set in the interrupt controller
The formula for calculating E_MDC clock frequency differs between MCF5272 and MPC860T:
— MCF5272: E_MDC_FREQUENCY= system frequency / (4 * MII_SPEED)
— MPC860T: E_MDC_FREQUENCY= system frequency / (2 * MII_SPEED)
Differences between MCF5272 FEC and MPC860T FEC
MCF5272 ethernet controller signal names are generally identical to those
used in the MPC860T, except for a prefix of ‘E_’. For example, MDC in the
MPC860T corresponds to E_MDC in the MCF5272.
