(1) Programmable polarity: shown as active LOW.
(2) Programmable polarity: shown as active HIGH.
(write) DATA [ 15:0 ]
(read) DATA [ 15:0 ]
DIOR or DIOW
= 1.65 V to 3.6 V; V
DREQ is continuously asserted, until the last transfer is done or the FIFO is full.
Data strobes: DIOR (read), DIOW (write).
read or write cycle time
DREQ set-up time before first DACK on
DREQ on delay after last strobe off
DREQ hold time after last strobe on
DIOR or DIOW pulse width
DIOR or DIOW recovery time
read data valid delay after strobe on
read data hold time after strobe off
write data hold time after strobe off
write data set-up time before strobe off
DACK set-up time before DIOR or DIOW assertion
DACK de-assertion after DIOR or DIOW de-assertion
