8. ddress Map organisation paragraph for details This type of memory has a limited number of writing cycles Also if this number is very high about 100000 cycles this limit can be easily reached if the storing process is forced through a serial communications line Please check that the storing procedure of these registers is not performed automatically This module allows parameters to be saved in a non volatile memory In order to avoid storing configuration data parameters registers 801 1000 by mista ke storage is only executed when a specific signature is written to the appro priate register The signature is ST Similarly the default values of parameters are restored On receipt of the correct signature in the appropriate register the device restores the default parameters The signature is RS The new configuration becomes active after a reset i e after a Power Down or a reset command signature RT See Register 400 es Node address change by serial communications 1 Write the new address in register 801 NodeA Write value 2 Write 0x5354 ASCII code ST to register 400 Store value 3 Write 0x5254 ASCII code RT to register 400 Cold reset The retentive device management data registers 401 800 are immediately valid after writing To maintain the values after a power OFF ON cyle the command Store ST must be executed Serial bus oe i channels 1 4 P
