LPC2930
ARM9 microcontroller with CAN, LIN, and USB
6.14.2
Clock Generation Unit (CGU0)
The key features are:
Generation of 9 base clocks, one test base clock, and two base clocks to drive CGU1,
selectable from several embedded clock sources
Crystal oscillator with power-down
Control PLL with power-down
Very low-power ring oscillator, always on to provide a safe clock
Seven fractional clock dividers with L/D division
Individual source selector for each base clock, with glitch-free switching
Autonomous clock-activity detection on every clock source
Protection against switching to invalid or inactive clock sources
Embedded frequency counter
Register write-protection mechanism to prevent unintentional alteration of clocks
Remark:
Any clock-frequency adjustment has a direct impact on the timing of all on-board
peripherals.
6.14.2.1
Functional description
The clock generation unit provides 10 internal clock sources as described in
Table 26
.

Maximum frequency that guarantees stable operation of the LPC2930.
[2]
Fixed to low-power oscillator.
For generation of these base clocks, the CGU consists of primary and secondary clock
generators and one output generator for each base clock.
