N
The DIV word sets the programmable divider. These 10 bits (N0–N9) determine the value of the
programmable divider (N). The range of divisor values is from two to 1025, and is equal to the
programmed value of N plus 2 (see Table 8).

*Factory Default Setting
ADDR BYTE
X = Don’t care.
A2, A1, A0 (Default Setting = 000)
These are the device select bits that determine the 2-wire address of the device.
WC (Default Setting = 0)
This bit determines when/if the EEPROM is written to after register contents have been changed. If
WC = 0, EEPROM is written automatically after a write register command. If WC = 1, the EEPROM is
only written when the “WRITE” command is issued. In applications where the register contents are
frequently rewritten, WC should be set to 1; otherwise, it is necessary to wait for an EEPROM write cycle
to complete (up to 10ms) between writing to the registers. Regardless of the value of the WC bit, when
the ADDR register (A2, A1, A0) is written, the current value in all registers (DAC, OFFSET, DIV, MUX,
and ADDR) are immediately written to the EEPROM.
RANGE REGISTER
The first five bits of the RANGE register contain the default OFFSET value. The decimal value of the
RANGE register is the value OS that is referred to in Table 6. The RANGE register is read-only.
