LPC2917/19
ARM9 microcontroller with CAN and LIN
There are two primary clock generators: a low-power ring oscillator (LP_OSC) and a
crystal oscillator. See
Figure 12
.
LP_OSC is the source for the BASE_PCR_CLK that clocks the CGU itself and for
BASE_SAFE_CLK that clocks a minimum of other logic in the device (like the watchdog
timer). To prevent the device from losing its clock source LP_OSC cannot be put into
power-down. The crystal oscillator can be used as source for high-frequency clocks or as
an external clock input if a crystal is not connected.
Secondary clock generators are a PLL and seven fractional dividers (FDIV0..6). The PLL
has three clock outputs: normal, 120
°
phase-shifted and 240
°
phase-shifted.
Configuration of the CGU:
For every output generator - generating the base clocks - a
choice can be made from the primary and secondary clock generators according to
Figure 13
.
