11.5.22 Initialization Sequence
This section describes which registers and RAM locations are reset due to hardware reset, which are reset
due to the FEC reset, and what locations the user must initialize before enabling the FEC.
As soon as the FEC is initialized and enabled, it operates autonomously. Typically, the driver writes only
to RDAR, TDAR, and EIR during operation.
11.5.22.1 Hardware Initialization
In the FEC, hardware resets only those registers that generate interrupts to the MCF5272 processor or
cause conflict on bidirectional buses. The registers are reset due to a hardware reset.
Other registers reset whenever the ETHER_EN bit is cleared. Clearing ETHER_EN immediately stops all
DMA and transmit activity after a bad CRC is sent, as shown in
11.5.23 User Initialization (Prior to Asserting ETHER_EN)
The user must initialize portions the FEC prior to setting the ETHER_EN bit. The exact values depend on
the particular application. The sequence is similar to the procedure defined in
