LPC2921/2923/2925
ARM9 microcontroller with CAN, LIN, and USB
Two of the base clocks generated by the CGU0 are used as input into a second,
dedicated CGU (CGU1). The CGU1 uses its own PLL and fractional dividers to generate
the base clock for the USB controller and one base clock for an independent clock output.

Base clock and branch clock relationship
Table 7
contains an overview of all the base blocks in the LPC2921/2923/2925 and their
derived branch clocks. A short description is given of the hardware parts that are clocked
with the individual branch clocks. In relevant cases more detailed information can be
