DMA Handshake
These specifications describe the three DMA handshake modes.
In all three modes, DMARx is used to initiate transfers. For
Handshake mode, DMAGx controls the latching or enabling of
data externally. For External handshake mode, the data transfer
is controlled by the ADDR31–0, RD, WR, PAGE, MS3–0, ACK,
and DMAGx signals. For Paced Master mode, the data transfer
is controlled by ADDR31–0, RD, WR, MS3–0, and ACK (not
DMAG). For Paced Master mode, the Memory Read-Bus Mas-
ter, Memory Write-Bus Master, and Synchronous Read/Write-
Bus Master timing specifications for ADDR31–0, RD, WR,
MS3–0, PAGE, DATA63–0, and ACK also apply.

W = (number of wait states specified in WAIT register)
tCK.
HI = tCK (if data bus idle cycle occurs, as specified in WAIT register; otherwise HI = 0).
1 Only required for recognition in the current cycle.
2 t
SDATDGL is the data setup requirement if DMARx is not being used to hold off completion of a write. Otherwise, if DMARx low holds off completion of the write, the data can
be driven tDATDRH after DMARx is brought high.
3 t
VDATDGH is valid if DMARx is not being used to hold off completion of a read. If DMARx is used to prolong the read, then tVDATDGH =tCK –0.25tCCLK –8+(n×tCK) where n equals
the number of extra cycles that the access is prolonged.
4 See Example System Hold Time Calculation on Page 47 for calculation of hold times given capacitive and dc loads.
5 For ADSP-21062/ADSP-21062L specification is –2.5 ns min, 2 ns max.
6 For ADSP-21060L/ADSP-21062L specification is –1 ns min.
