11. Corrections for RCNT—Refresh Counter Period Description.
On page 6-64, section 6.13.1, make the following corrections:
a) ‘RFCNT’ in the equation should be ‘RCNT’.
b) ‘24 (decimal)’ in the example should be ‘23 (decimal)’.
c) ‘24 / (25 MHz / 16)’ in the example should be ‘(23 + 1) / (25 MHz / 16)’.
12. Typo on Global Memory Register.
On page 6-65, section 6.13.1, the following should replace the definition of PGS2-PGS0:
PGS2–PGS0—Page Size
This attribute determines the page size and AMUX for the DRAM controller (see Table 6-
9). For multiplexing information see Table 6-8 on page 6-59. The page size is the smallest
DRAM size the user needs to support page mode capability.
Delay Write QUICC Bit Definition.
On page 6-66, section 6.13.1, the description of the DWQ bit was not clear. The bit definition
should be replaced as follows:
DWQ—Delay Write for QUICC (DRAM Bank Only)
This attribute is used to add a clock to the assertion and negation of the CAS signal on
DRAM page hit write cycles. The write cycle lasts one additional clock in this case. This
attribute is applicable to an internal QUICC master and to an external MC68030/QUICC.
0 = Reads and writes are the same length.
1 = Add one clock to write cycles for DRAM banks.
NOTE
This bit must be set by the user if page mode is enabled for this
DRAM bank (PGME = 1), and when a zero wait state DRAM is
implemented by setting TCYC to be zero. If this is not done the
DRAM may latch invalid data during writes.
