3. Once the field upgrade process begins, the
STC5423 is hold for data loading. Write 7600
bytes firmware configuration data to the register
Field Upgrade Data one byte at a time to com-
plete data loading. User can read the same regis-
ter for the written byte. But no matter how many
times the user read, only the last written byte will
be read from the register.
4. Read the register Field Upgrade Count for how
many bytes of configuration data has been loaded.
Bit Load_Compelet of the register Field Upgrade
Status will indicate whether the 7600 bytes loading
is complete and meanwhile bit CHECKSUM will
indicate the loading is failed or succeed. See regis-
ter description of Field Upgrade Status for details.
