The DSP56002 system clock may be derived from the on-chip crystal oscillator as
shown in Figure 2-2, or it may be externally supplied. An externally supplied square
wave voltage source should be connected to EXTAL, leaving XTAL physically
unconnected to the board or socket. The rise and fall times of this external clock
should be 4 ns maximum.
