LPC2917/01; LPC2919/01
ARM9 microcontroller with CAN and LIN
6.15.2
Clock Generation Unit (CGU0)
The key features are:
Generation of 11 base clocks, 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.
6.15.2.1
