ECC1_SNG_ERR
If a single error is detected in the EEPROM stored data, the
ECC1_SNG_ERR bit is set to 1 when read. A single error can be
detected and corrected using the error correcting code
employed by the
ADuM4138
. ECC1_SNG_ERR shows that a
single error is detected in the memory banks representing trim
performed on the parts by the user trim address and the
configuration trim address. A value of 0 means no error is
detected.
Prog_Busy
Set this bit high in order to program the EEPROM memory.
When this bit is set to 1, the EEPROM begins to write to
memory. The hardware sets this bit back to 0 to indicate that
programming has occurred. The write sequence takes a
maximum of 40 ms (maximum) to perform, but may write
faster than 40 ms (maximum). If shorter wait times are desired,
the Prog_Busy bit can be read back multiple times during the
writing time. If a 0 is read back after the user sets the bit to 1,
the writing is complete.
Sim_Trim
If Sim_Trim is set to 0, the user trim and configuration trim
registers have no effect. Use this bit to simulate trim settings
without writing to the registers.
