Serial Cable Assembly (Emerson part number C00003555-xx)
Caution:
The USB mini-B cable connection to P17 does not have a locking mechanism. Pulling on the
cable may result in a disconnection.

BAUD RATE SELECTION
The eight internal baud rate generators are contained in the MPC8560 Communications
Processor Module (CPM). They can deliver a maximum baud rate at one half of the system
clock rate and may be changed on-the-fly. Each baud rate generator may be routed to mul-
tiple FCCs or SCCs.
An external Voltage Controller Oscillator (VCO) provides the input frequency for the internal
MPC8560 baud rate generators. This frequency is divided down to generate the console
port frequencies. The baud rate is calculated from the PCI clock/SysCLK—optimal speeds
include 33 MHz and 66 MHz.
Table 5-3
lists the clock divider values associated with typical
baud rates for both 33 MHz and 66 MHz clocks.
