MPC8313E RDB Board Configuration

This section describes the operational frequency and configuration options of the MPC8313E RDB.
5.1
An M66EN input pin determines the frequency of the PCI interface. On the MPC8313E RDB, the M66EN
signal level is determined by the PCI agent card connected to the miniPCI or PCI slot. If a 33 MHz-only
card is inserted, the M66EN signal is driven to 0 by the PCI agent card according to the PCI specification.
However, it is pulled to 1 if it can perform at 66 MHz. By default, the MPC8313E RDB runs its PCI
interfaces at 66 MHz unless a 33-MHz PCI card is inserted.
5.2
The reset configuration word (RCW) controls the clock ratios and other basic device functions such as PCI
host or agent mode, boot location, and endian mode. The reset configuration word is divided into reset
