N
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 are the device select bits that determine the address of the device.
(Default Setting = 000)
WC
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.
(Default Setting WC = 0)
