VersaClock 6E Family Register Set

The device contains volatile (RAM) 8-bit registers and non-volatile 8-bit registers
Programmable (OTP), and bit values can only be changed from 1 (unburned state) to 0.
The OTP registers include factory trim data and four user configuration tables
format or methods for programming factory trim data, which is programmed by the factory before shipment.
Each configuration table contains all the information to set up the device's output frequencies. When these configuration tables are
programmed, the device will automatically load the RAM registers with the desired configuration on power-up. The device initializes in
2
either I C mode or selection-pin mode, depending on the state of the OUT0/SELB_I2C pin on power-up, and remains in the selected
mode until power is toggled
selection-pin mode, the SEL0 and SEL1 inputs are decoded to select one of the four configuration tables CFG0-CFG3.
The RAM registers (Table 4) include Status registers for read-back of the device's operating conditions in I
