0xFFE0 8208, 228, 248, 268)
The EMCStaticWaitOen0-3 registers enable you to program the delay from the chip select
or address change, whichever is later, to the output enable. It is recommended that these
registers are 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. These registers are accessed with one wait state.
Table 5–91
Table 91.
0xFFE0 820C, 22C, 24C, 26C)
The EMCStaticWaitRd0-3 registers enable you to program the delay from the chip select
to the read access. It is recommended that these registers are 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. It
is not used if the extended wait bit is enabled in the EMCStaticConfig0-3 registers. These
registers are accessed with one wait state.
