o) User-writable data space (EEPROM name: UE)

Free area (EEPROM) available to the user.

Address : 12 hex D[7:0] = EUE[7:0]

Name Content

Data

D7 D6 D5 D4 D3 D2 D1 D0

User-writable data

Default 0 0 0 0 0 0 0 0

p) Control register access setup (EEPROM name: MM3)

The access setup to the control register (volatile memory) is performed.

When the control register access setup is disabled (ETST[0] = 0h), the control register (C address:

0h) is fixed to the initial value, and cannot be accessed, unless control register access is validated.

Address : 1D hex D[0] = ETST[0]

D[0] Symbol Mode setup

D[0] ETST[0] Control register access setup

0 TSTDS Control register access disable(default)

1 TSTEN Control register access enable

q) EEPROM Write Enable setup (EEPROM name: EWE)

The EEPROM write enable setup is performed.

When the setup of EEPROM Write Enable is validated (EWE[0] = 1h), the writing to EEPROM is

permitted. If it is invalid, the writing to EEPROM other then EEPROM Write Enable (address: 00

-1Dh, 1Fh) becomes impossible. And this address cannot be written by batch writing. However,

EEPROM read (all the addresses) is possible even in that case.

Address : 1E hex D[0] = EWE[0]

D[0] Symbol Mode setup

D[0] EWE[0] EEPROM Write Enable setup

0 WEDS EEPROM Write disable (default)

1 WEEN EEPROM Write enable

r) EEPROM batch write mode (EEPROM name: AW)

Initializes the addresses 00 hex to 1D hex in the EEPROM map at once or writes identical data. This

address is not available in the EEPROM.

Address : 1F hex D[7:0] = EAW[7:0]
