6.4.1 Register Transfers / PIO Data Transfers
Notes:
1. Device address consists of signals CS0_, CS1_ and DA(2:0).
2. Data consists of IODD(7:0).
3. The negation of IORDY by the device is used to extend the register transfer cycle. The determination of
whether the cycle is to be extended is made by the host after t
A
from the assertion of DIOR_ or DIOW_.
The assertion and negation of IORDY are described as following:
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.
