Product data
Fig 24. GDMA slave mode timing (BURST = 01H, MODE = 02H).
Fig 25. GDMA slave mode timing (BURST > 01H, MODE = 00H).
DREQ is asserted for every transfer.
Data strobe: DACK (read/write).
(1) Programmable polarity: shown as active LOW.
(2) Programmable polarity: shown as active HIGH.
DREQ is asserted once per N transfers (N is determined by the BURST value). Example shown here: N = 2.
Data strobes: DIOR (read), DIOW (write).
(1) Programmable polarity: shown as active LOW.
(2) Programmable polarity: shown as active HIGH.
