Reset, Clocking, and Initialization

The following external clock sources are utilized on the MPC8313E:
All clock inputs can be supplied using an external canned oscillator, a clock generation chip, or some other
source that provides a standard CMOS square wave input.
The system and USB clock sources can alternatively be provided using an external crystal (on-chip crystal
oscillator provided). Separate crystal (CR) inputs/outputs are provided for this case. The crystal oscillator
dissipates 50 mW of current, so this may not be the best choice for very low power applications. When a
crystal is not used, a square wave clock input must be supplied.
If SYS_CLK_IN is used as the system clock, the SYS_CR_CLK_IN (crystal input) must be tied to quiet
ground; otherwise, SYS_CLK_IN must be tied to quiet ground. Similarly, if USB_CLK_IN is used as the
USB clock, USB_CR_CLK_IN (crystal input) must be tied to quiet ground; otherwise, USB_CLK_IN
must be tied to quiet ground.
