The results of this power-on test are reported in the ID1 and ID0 bits, as shown in
Table 4-3.
Other EEPROM devices (with device address of 1010) can be attached to the I
general purpose 8051 use, as long as they are strapped for address other than 000 or 001.
If a 24LC00 EEPROM is used, no other EEPROMS with device address 1010 may be
used, because the 24LC00 responds to all eight sub-addresses.
