LPC2926/2927/2929
ARM9 microcontroller with CAN, LIN, and USB
6.16.3
Clock generation for USB (CGU1)
The CGU1 block is functionally identical to the CGU0 block and generates two clocks for
the USB interface and a dedicated output clock. The CGU1 block uses its own PLL and
fractional divider. The PLLs used in CGU0 and CGU1 are identical (see
Section 6.16.2.2
).
The clock input to the CGU1 PLL is provided by one of two base clocks generated in the
CGU0: BASE_ICLK0_CLK or BASE_ICLK1_CLK. The base clock not used for the PLL
can be configured to drive the output clock directly.
6.16.3.1
Pin description
The CGU1 module in the LPC2926/2927/2929 has the pins listed in
