... To simplify traditional loop counter setting, the PLL202-16 device incorporates SMART-BYTE ™ technology with a single byte programming via I2C. Detail of PLL202-16's dual mode frequency programming method is described below: 1. ROM-table Frequency Programming: The pre-defined 32 frequencies found in Frequency table can be accessed through 3 external jumpers. ...

... WDT will generate a 500ms low watchdog reset pulse to provoke a system reset. After system restarts, the PLL202-16 will start from predefined Fall-back Frequency (the value of I2C Byte6, bits(7:3)). If system for any reason fails again at Fall-back Frequency, the internal hardware will then generate a watchdog reset to restart the system from the value of external hardware jumper setting to ensure a safe recovery ...
