FUNCTIONAL BLOCKS
The HW400c/2 has six major functional blocks – the PowerPC processor, system
controller, CT Bus interface, Ethernet switch, PTMC expansion sites, and the IPMI
controller. The following sections describe these functional blocks in greater detail.
Additional features such as the connector pin outs and JTAG development support
are also described.

3.1 PowerPC Processor
The standard configuration for the HW400c/2 includes the Freescale MPC7447A
PowerPC Processor running at 1000 MHz (1 GHz) with a corresponding system bus
speed of 166 MHz. There are two additional processor variants available for the
board, which utilize the Freescale MPC7448 PowerPC Processor with a 200 MHz
system bus speed.
The operating frequency and power consumption for each processor variant is shown
in Table 6.

3.1.1 MPC744X Development/Debug Support
The HW400c/2 provides external access to the MPC744X processor COP port, reset
and interrupt signals at headers J6, Jx6, J7, J8, and J9 (See Figure 2). A console port
is also provided on the front panel of the board though an RJ45 modular connector
(see Figure 4, and Section 3.1.2).
