Clock Generation Unit
The Clock Generation Unit (CGU) allows great flexibility in the clock generation for the
XC886/888. 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 XC886/888, the oscillator can
be from either of these two sources: the on-chip oscillator (9.6 MHz) or the external
oscillator (4 MHz to 12 MHz). The term “oscillator” is used to refer to both on-chip
oscillator and external oscillator, unless otherwise stated. After the reset, the on-chip
oscillator will be used by default.The external oscillator can be selected via software. 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.
1) BSL mode is automatically entered if no valid password is installed and data at memory address 0000H equals
zero.
2) OSC is bypassed in MultiCAN BSL mode
3) Normal user mode with standard JTAG (TCK,TDI,TDO) pins for hot-attach purpose.
