The controller is set with 4Mbytes (1Mx32bits) of SDRAM memory and 2Mbytes of flash memory. The
SDRAM is a volatile memory which is erased each time the controller is switched OFF, whereas the flash is a
non-volatile memory and the data which is stored in it is not lost when the controller is switched OFF. All
calculations and operations done by the controller are made with SDRAM values.
SAV, RES and NEW commands allow the user to transfer data from the SDRAM to the flash and vice-versa.
The SAV command (SAVe) saves into the “flash” memory the controller’s data (like registers, sequences,
...), so that they are not lost when the controller is switched off and on again. Saved data is defined by the first
parameter.
The RES command (REStore) rereads the controller’s data (like registers, sequences,...), previously saved
with SAV command into the “flash” memory, and restores them into the SDRAM memory. Restored data is
defined by the first parameter.
The NEW command reloads in the SDRAM the default values of parameters K, or erases the S user sequence
stored in the SDRAM, depending on the first parameter's value.
Caution: After executing RES and NEW commands, SDRAM ordinary values are replaced by the values
read in the “flash” memory and are definitively lost. Similarly, the SAV command crushes the
values contained in ’flash’ with those contained in the SDRAM. To avoid possible problems,
SAV, RES and NEW commands should be executed if the controller is in ’Power Off’.
