Description

EDDS

R/W

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

DRAM/SDRAM is enabled only in full access mode

1: EXDMAC single address transfer through the

DRAM/SDRAM is also enabled in fast-page access

mode
