Parameter
When On, the interface includes a
writeresponse
pin.
On/Off
Off
Use the writeresponse signal
When On, the interface includes a
readresponse
pin.
On/Off
Off
Use the readresponse signal
When On, the interface includes a
clken
pin.
On/Off
Off
Use the clken signals
Burst Attributes
When On, the address for bursts wraps instead of an
incrementing. With a wrapping burst, when the
address reaches a burst boundary, it wraps back to the
previous burst boundary. Consequently, only the low
order bits are used for addressing.
On/Off
On
Linewrap burst
When On, memory bursts are aligned to the address
size.
