2.2 SCI-A LIN MASTER
With the ST92F150 emulator, the prescaler must be increased before sending the Synch
Break and decreased before sending the Synch Field. For instance:
– Fcpu=24MHz, Normal Prescaler=75, BaudRate=20kbps. BitLength=50us, Synch-
– Fcpu=24MHz, Synch Break Prescaler=95, BaudRate=15.8kbps. BitLengh=63.33us, Break-
The second configuration can be used for the Synch Break generation and the first one for the
other part of the LIN frame (Synch field, data and CRC).
This prescaler modification is only used for the application development using the emulator.
The final ST92F250 application uses just one prescaler and sets the LINE bit in the SCI-A in-
itialization code.
2.3 SECOND I2C
The I2C-1 cannot be emulated but the code validation can be done as a separate application
using the I2C-0.
When the I2C-1 is being used, external addresses A[18:17] are no longer available. This is not
the case with the ST92F150 emulator as the second I2C is not available. Take care not to use
these addresses.
2.4 EXTERNAL MEMORY ACCESS
The external memory access should be emulated with EMR1.BSZ bit=0.
This will configure the P4[7:6]-P6[5:4] signals in Standard mode. If High Drive mode is needed
for the I2C communication (with EMR1.BSZ bit=1), it should be emulated separately from the
external memory access (with EMR1.BSZ bit=0).
2.5 P3.0, P6.6 AND P6.7
These general purpose I/Os cannot be emulated.
2.6 TOOLCHAIN INCLUDE FILES
All the ST92F250 features are described in the STVD9 V6 ToolChain include files.
Use the following statement:
#include <sys\st92f250\st92f250.h>
#include <sys\st92f250\flash.h>
#include <sys\st92f250\i2c0.h>
#include <sys\st92f250\i2c1.h>
Break=500us.
Length=506us.
