... Programmable Clock Generator for VIA, ALI and SIS DDR SYSTEM PROGRAMMING OF CPU FREQUENCY Using Smart- Byte: To simplify traditional loop counter setting, the PLL202-151 device incorporates SMART -BYTE ™ technology with a single byte programming via I2C. Detail of PLL202-151'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 4 external jumpers ...

... WDT will generate a 500ms low watchdog reset pulse to provoke a system reset. After system restarts, the PLL202-151 will start from predefined Fall-back Frequency (the value of I2C Byte9, bits(5:3)). 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 ...
