beginning of the cycle to the assertion of the write signals (CSToWr), the number of cycles the write is active (WrAc-
tive), and the number of cycles the write signals are inactive (WrHigh) between consecutive writes in a burst access.
The Ready* signal that can be used to insert wait states to each device data transfer can be enabled/disabled per bank
via the Ready field.

TurnOff
The number of cycles between the deassertion of
DevCS* and a new AD bus cycle.
0x3
4:2
AccToFirst
The number of cycles from DevCS* active to first data
(determined by the access time of the device).
Actual value is n+2 (‘00’ is not allowed).
0x7
7:5
AccToNext
The number of cycles between the sampling of data
and the next sampling point of data (time difference
between sampling points in a burst sequence).
Actual value is n+1.
0x7
9:8
CSToWr
The number of cycles from DevCS* to first assertion
of WrEn*
Actual value is n+2 (‘00’ is not allowed).
0x3
11:10
WrActive
The number of cycles WrEn* is active.
Actual value is n+1.
0x3
13:12
WrHigh
The number of cycles between deassertion and
assertion of WrEn*.
Actual value is n+1 (‘00’ is allowed for 32-bit devices
only).
0x3
14
Ready
Controls bus cycle extension, can be disabled by
DevCS*.
0 - Enabled, will extend the bus cycle
1 - Disabled
0x0
