LPC2917/19
ARM9 microcontroller with CAN and LIN
[1]
This clock is always on (cannot be switched off for system safety reasons)
[2]
In the peripheral subsystem parts of the Timers, Watchdog Timer, SPI and UART have their own clock 
source. See 
 for details.
[3]
In the Power Clock and Reset Control subsystem parts of the CGU, RGU PMU have their own clock 
source. See 
 for details.
[4]
The clock should remain activated when system wake-up on timer or UART is required.
