DUTY-CYCLE Register
(DUTY_CYCLE)
The DUTY_CYCLE register is a 4-bit read/writable reg-
ister used to control the duty cycle of the V
OUT
output.
The controllable duty cycle range via this register is
30% to 100%, with programming steps of 4.67%.This
method of duty cycle control is mainly used with the
SMBus interface. However, if the V
IN
method of duty
cycle control has been selected (or defaulted to), and
the V
IN
pin is open, the duty cycle will go to the default
setting for this register, which is
0010
(39.33%). The
duty cycle settings are shown in Register 6-5.

Manufacturer’s Identification
Register (MFR_ID)
This register allows the user to identify the manufac-
turer of the part. The MFR_ID register is an 8-bit Read
only register. See Register 6-6 for the Microchip manu-
facturer ID.

6.7
Version ID Register (VER_ID)
This register is used to indicate which version of the
device is being used, either the TC664 or the TC665.
This register is a simple 2-bit Read only register.
