3.1 Device never negates IORDY, devices keeps IORDY released: no wait is generated.
3.2 Device negates IORDY before t
A
, but causes IORDY to be asserted before t
A
. IORDY is
released prior to negation and may be asserted for no more than 5 ns before release: no
wait generated.
3.3 Device negates IORDY before t
A
, IORDY is released prior to negation and may be
asserted for no more than 5 ns before release: wait generated. The cycle completes after
IORDY is released. For cycles where a wait is generated and DIOR_ is asserted, the
device shall read data on IODD(0:7) for t
RD
before asserting IORDY.
4. DMACK_ shall remain negated during a register transfer.
