Safety Manual for MPC5777M, Rev. 1.1
Address decoding coverage
NXP Semiconductors74
To determine the reading order of the other locations of these 2 word-lines the following principles shall
be considered:
• Alternate reads between the 2 word-lines starting from the word-line of the complementary
address.
• First, read from columns close to the victim address; second, a column close to the complementary
address, and so on.
Table 14 shows an example about the required reading order for victim and complementary rows. No
ordering requirements for the remaining locations.
To summarize:
• All grey locations of this table shall be read
• Reading of victim and complement word-lines shall follow a specific order.
