In the Intel mode microport, the beginning of a read and
write access is indicated by the RDY pin going low. The
access is complete only when the RDY pin goes high. In the
Motorola mode microport, the completion of a read and
write access is indicated by the DTACK pin going low. In
both modes, CS , RD ( DS ), and WR (R/ W ) should be active
until access is complete; otherwise, an incomplete access
results.
In both Intel and Motorola modes, if CS is held low even
after microport read or write access is complete, the

microport initiates a second access. This is a problem while
writing or reading from coefficient RAM, where each access
writes to or reads from a different RAM address. This can
be fixed by writing to one coefficient RAM address at a
time, that is, the coefficient start and stop address registers
have the same value.
In SPI mode programming, the SCS pin must go high
(inactive) after writing or reading each byte (eight clock
cycles on the SCLK pin).
