MC68360 USER’S MANUAL ERRATA
MOTOROLA
Section 5– CPU32+
1. Error in figure
On page 5-3, the data bus on figure 5-1 shows the data bus to be 16 bit. This is not correct,
the data bus on the QUICC is 32 bit wide.
Section 6 – System Integration Module
1. Added Information On Crystal Operation.
On page 6-13 the following sections should be added:
6.5.1.1 Using Oscillator as Input Clock
The preferred mode of operation of the 68360 is by driving the EXTAL pin with the output of
an oscillator. Oscillators are more costly than crystal circuits but are not subject to the same
sensitivity as crystal circuits. You have the choice of using a full speed oscillator (i.e. 25 MHz
oscillator) or using a lower speed oscillator such as 4 MHz or 32 kHz and having the system
frequency generated by the on-board PLL. Use of a lower speed oscillator will allow your
system to draw less power in a power-down mode.
NOTE
There are some limits to the speed of the oscillator that you can
use in certain situations. Please see Additional Information:
Phase Lock Loop for a description of these special situations.
6.5.1.2 Using Crystal as Input Clock
The 68360 has the ability to use a low speed crystal as its clock source. The on-chip PLL
can multiply the output of the crystal circuit up to the final system frequency. A crystal circuit
consists of a parallel resonant crystal, two capacitors, and two resistors. Example values for
both a 32kHz crystal and a 4MHz crystal are shown in Figures 6-6 and 6-6A. Note that these
are example values. Your circuit may require slightly different values to operate properly.
Crystals are typically much cheaper than similar speed oscillators. However, they may not
be as stable since they are affected by parameters such as: trace length, component quality,
board layout, 68360 package type, 68360 shrink level, etc. While crystal circuits are typically
stable, it is impossible to guarantee that they will remain stable due to 68360 process
changes or external component shifts.

NOTE
The internal frequency of the 68360 and the output of the CLKO
pins is dependent upon both the quality of the crystal circuit and
the multiplication factor (MF) used in the PLLCR register. Please
