Tightly-Coupled Memory Interface
5-6
DRWD[31:0]
DRWD is the write data written into the TCM. It is valid in the same cycle as DRCS
and held stable until the penultimate cycle of the access.
DMA signals
The DMA interface allows the values of DRADDR and DRCS to be generated from a
source external to the ARM926EJ-S processor.
DRDMAEN
DRDMAEN is the DMA enable signal. When asserted it indicates that the DMA values
should be used to produce DRCS and DRADDR rather than those from the internal
ARM926EJ-S TCM controller.
DRDMACS
DRDMACS is used to generate DRCS when DRDMAEN is asserted. Because of the
way the DRDMACS signal is combined with the internal ARM926EJ-S TCM
controller, it is not valid to assert DRDMAEN without DRDMACS asserted unless the
internal TCM controller is idle (DRIDLE asserted). The relationship between these
signals is shown in Table 5-1.
DRDMAADDR[17:0]
DRDMAADDR is used as the source for DRADDR whenever DRDMAEN is
asserted.
