• Manufacturer Part Number: DS1077
• Description: EconOscillator/Divider
• Manufacturer: DALLAS [Dallas Semiconductor]

DIV WORD
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).
PROGRAMMABLE DIVISOR N VALUES Table 5
**Default Condition
BUS WORD
*These bits are reserved and must be set to zero.
A0, A1, A2
These are the device select bits that determine the address of the device.
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.
