Table 99. Register 0xD2—EEPROM_NUM_RD_BYTES

Bits

Bit Name/Function

R/W

Description

[7:0]

Number of read bytes

returned

R/W

These bits set the number of read bytes that are returned when the EEPROM_DATA_xx commands are

used.

These bits set the address offset of the current EEPROM page.

EEPROM_PAGE_ERASE

Table 101. Register 0xD4—EEPROM_PAGE_ERASE

Bits

Bit Name/Function

R/W

Description

[7:0]

EEPROM page erase

Perform a page erase on the selected EEPROM page (Page 3 to Page 15). Wait 35 ms after each

page erase operation. The EEPROM must first be unlocked.

Page 0 and Page 1 are reserved for storing the default settings and user settings, respectively. The

user cannot perform a page erase of Page 0 or Page 1.

Page 2 is reserved for internal use; do not erase the contents of Page 2.

Page 3 is reserved for storing the board parameters for GUI use; erase Page 3 before storing the

board parameters.

The following list shows the register setting used to access each page:

0x03 = Page 3.

0x04 = Page 4.

0x05 = Page 5.

0x06 = Page 6.

0x07 = Page 7.

0x08 = Page 8.

0x09 = Page 9.

0x0A = Page 10.

0x0B = Page 11.

0x0C = Page 12.

0x0D = Page 13.

0x0E = Page 14.

0x0F = Page 15.

Table 102. Register 0xD5—EEPROM_PASSWORD

Bits

Bit Name/Function

R/W

Description

[7:0]

EEPROM password

Writes the password using this command to unlock the EEPROM for read/write access. Writes the

EEPROM password two consecutive times to unlock the EEPROM. Writes any other value to exit.

The factory default password is 0xFF.

TRIM_PASSWORD

Table 103. Register 0xD6—TRIM_PASSWORD

Bits

Bit Name/Function

R/W

Description

[7:0]

Trim password

Writes the password using this command to unlock the trim registers for write access. Writes the

trim password two consecutive times to unlock the registers. Writes any other value to exit. The trim

password is the same as the EEPROM password. The factory default password is 0xFF.
