Address 0Eh igc_done_xtdinit igc_done_ism wr_full_done rd_full_done spim_eebusy spim_eestat spim_wr_done spim_rd_done
Default value= 00h.
These flags can only be set by the chip. They can only be cleared by writing a zero to the desired location.
spim_rd_done = Read from EEPROM complete.
spim_wr_done = Write to EEPROM complete.
spim_eestat = EEPROM status read complete.
spim_eebusy = EEPROM busy caused abort of attempted read/write.
rd_full_done = Full read from EEPROM complete.
wr_full_done = Full write to EEPROM complete.
igc_done_ism = Initialization sequence complete.
igc_done_xtdinit = Extended initialization sequence complete.
Description: Status flags for data transfers to/from EEPROM.
