EEPROM REGISTER
The format of the EEPROM Register is shown in Figure 11. The function of each bit is described in
detail in the following paragraphs.
EEPROM REGISTER FORMAT Figure – 11
EEC – EEPROM Copy Flag. A 1 in this read-only bit indicates that a Copy Data command is in
progress. While this bit is high, writes to EEPROM addresses are ignored. A 0 in this bit indicates that
data may be written to unlocked EEPROM blocks.
LOCK – EEPROM Lock Enable. When this bit is 0, the Lock command is ignored. Writing a 1 to this
bit enables the Lock command. After the Lock command is executed, the LOCK bit is reset to 0.
BL1 – EEPROM Block 1 Lock Flag. A 1 in this read-only bit indicates that EEPROM Block 1
(addresses 30-3F) is locked (read-only) while a 0 indicates Block 1 is unlocked (read/write).
BL0 – EEPROM Block 0 Lock Flag. A 1 in this read-only bit indicates that EEPROM Block 0
(addresses 20-2F) is locked (read-only) while a 0 indicates Block 0 is unlocked (read/write).
X – Reserved bits.
SPECIAL FEATURE REGISTER
The format of the Special Feature Register is shown in Figure 12. The function of each bit is described in
detail in the following paragraphs.
SPECIAL FEATURE REGISTER FORMAT Figure – 12
PIO – PIO Pin Sense and Control. See the Programmable I/O section for details on this read/write bit.
MSTR - SWAP Master status bit. This bit indicates whether a device has been selected through the
SWAP command. Selection of this device through the SWAP command and the appropriate Net Address
will result in setting this bit, indicating that this device is the master. A 0 signifies that this device is not
the master.
X – Reserved bits.
PS – PS Pin Mirror. This read-only bit mirrors the state of the PS pin.
