The Clock Generation Unit (CGU) allows great flexibility in the clock generation for the
XC864. The power consumption is indirectly proportional to the frequency, whereas the
performance of the microcontroller is directly proportional to the frequency. During user
program execution, the frequency can be programmed for an optimal ratio between
performance and power consumption. Therefore the power consumption can be
adapted to the actual application state.
Features:
• Phase-Locked Loop (PLL) for multiplying clock source by different factors
• PLL Base Mode
• Prescaler Mode
• PLL Mode
• Power-down mode support
The CGU consists of an oscillator circuit and a PLL.In the XC864, the oscillator is the on-
chip oscillator (10 MHz). In addition, the PLL provides a fail-safe logic to perform
oscillator run and loss-of-lock detection. This allows emergency routines to be executed
for system recovery or to perform system shut down.
