Description
EXDMAC Single Address Transfer Option
Selects whether an EXDMAC single address transfer
through the DRAM/SDRAM interface is enabled only in
full access mode or is also enabled in fast-page access
mode.
When clearing the BE bit to 0 to disable a burst access
to the DRAM/SDRAM interface, an EXDMAC single
address transfer is performed in full access mode
regardless of this bit.
This bit does not affect an external access by other bus
masters or an EXDMAC dual address transfer. Setting
this bit to 1 changes the EDACK output timing.
0: EXDMAC single address transfer through the
1: EXDMAC single address transfer through the
Reserved
The initial value should not be changed.
DRAM/SDRAM is enabled only in full access mode
DRAM/SDRAM is also enabled in fast-page access
mode
