– User Procedure
– Slow Clock Mode Transition
Reload User Configuration Wait State
Figure 27-20. Early Read Wait State: NWE-controlled Write with No Hold Followed by a Read
The user may change any of the configuration parameters by writing the SMC user interface.
When detecting that a new user configuration has been written in the user interface, the SMC
inserts a wait state before starting the next access. The so called “Reload User Configuration
Wait State” is used by the SMC to load the new set of parameters to apply to next accesses.
The Reload Configuration Wait State is not applied in addition to the Chip Select Wait State. If
accesses before and after re-programming the user interface are made to different devices
(Chip Selects), then one single Chip Select Wait State is applied.
On the other hand, if accesses before and after writing the user interface are made to the same
device, a Reload Configuration Wait State is inserted, even if the change does not concern the
current Chip Select.
To insert a Reload Configuration Wait State, the SMC detects a write access to any MODE reg-
ister of the user interface. If the user only modifies timing registers (SETUP, PULSE, CYCLE
registers) in the user interface, he must validate the modification by writing the MODE, even if no
change was made on the mode parameters.
A Reload Configuration Wait State is also inserted when the Slow Clock Mode is entered or
exited, after the end of the current transfer (see

signal(NWE)
