Addendum for Revision 2.0
Freescale Semiconductor 2
1 Addendum for Revision 2.0
Table 1. MPC5566RM Rev 2.0 addendum
Location Description
Section 12.4.2.7/Page 12-50 Change sentence “The bytes indicated as ‘—’ are not driven during that write cycle” to read “The
bytes indicated as ‘—’ are indeterminate and may be driven during that write cycle.”
Table 12-21, “Data Bus
Contents for Write
Cycles”/Page 12-50
Replace table with the one below to correct information about data bus contents for write cycles.
Note that only two columns have changed: under “32-Bit Port Size,” columns “D0:D7” and
“D8:D15.”
Table 9-23, “DMA Request
Summary for eDMA”/Page
9-43
Change two rows in the table to correct information about eSCI COMBTX DMA request.
Only the Transmit Data Register Empty and LIN Transmit Data Ready flags drive the DMA
request. The Transmit Complete flag is not used.
