Errata and Added Information to
MC68360 Quad Integrated Communication
Controller User's Manual Rev 1
January 8, 1998
This document describes the latest information and changes to the first revision of the
MC68360 user's manual.
Section 2 – Signal Descriptions
1. QUICC Functional Signal Groups.
On page 2-2, Figure 2-1, the signal names in the left column had a typo. The corrections for
the typo are in the right column.
As seen on page 2-2
A31-A27/WE3-WE0
SDACK2/L1TSYNCB/CTS3/PC8
L1RSYNB/CD3/PC9
SDACK1/L1TSYNCA/CTS4/PC10
L1RSYNCA/CD4/PC11
2. Error on TRIS
On page 2-4, Table 2-1, the function description of TRIS stated that it is sampled during
system reset. This is not true. The TRIS signal is always sampled except during reset.
3. Missing Note.
On page 2-8, section 2.1.7.2 the following note should be added:
User should note that the pin AVEC/IACK5 is always an open
drain output.
