These ten bits determine the value of the programmable divider (N). The range of divisor values is from 2

to 1025, and is equal to the programmed value of N plus 2 (see Table 5).

*These bits are reserved and must be set to zero.

A0, A1, A2

(Default Setting = 000)

These are the device select bits that determine the address of the device.

WC

(Default Setting WC = 0)

This bit determines when/if the EEPROM is written to after register contents have been changed.

If WC = 0 the EEPROM is written automatically after a write register command.

If WC = 1 the EEPROM is only written when the “WRITE ” command is issued.

Regardless of the value of the WC bit, the value of the BUS Register (A0, A1, A2) is always written

immediately to the EEPROM.
