10.10 Dynamic Memory Last Data Out to Active Time register
10.11 Dynamic Memory Data-in to Active Command Time register
Table 76.
(EMCDynamictAPR - 0xFFE0 803C)
The EMCDynamicTAPR register enables you to program the last-data-out to active
command time, tAPR. It is recommended that this register is modified during system
initialization, or when there are no current or outstanding transactions. This can be
ensured by waiting until the EMC is idle, and then entering low-power, or disabled mode.
This value is normally found in SDRAM data sheets as tAPR. This register is accessed
with one wait state.
Note: This register is used for all four dynamic memory chip selects. Therefore the worst
case value for all of the chip selectsmust be programmed.

Table 77.
(EMCDynamictDAL - 0xFFE0 8040)
The EMCDynamicTDAL register enables you to program the data-in to active command
time, tDAL. It is recommended that this register is modified during system initialization, or
when there are no current or outstanding transactions. This can be ensured by waiting
until the EMC is idle, and then entering low-power, or disabled mode. This value is
normally found in SDRAM data sheets as tDAL, or tAPW. This register is accessed with
one wait state.
Note: This register is used for all four dynamic memory chip selects. Therefore the worst
case value for all of the chip selects must be programmed.
