External Clock Operation
The DSP56724/DSP56725 system clock is derived from the on-chip oscillator or is externally supplied. To use the on-chip
oscillator, connect a crystal and associated resistor/capacitor components to EXTAL and XTAL; see Figure 6.
Figure 6. Using the On-Chip Oscillator
If the DSP56724/DSP56725 system clock is an externally supplied square wave voltage source, it is connected to EXTAL
(Figure 7). When the external square wave source is connected to EXTAL, the XTAL pin is not used.
