I use tms320vc549, I have some problems in bootloader and PLL mode, my=20
problems are:
1- In spru131 =E2=80" part 8.5 =E2=80" table 8.15 (Clock mode): when I use =
crystal=20
for clocking, which of =E2=80=9Cwith external source=E2=80=9D or =E2=80=9Cw=
ith oscillator=20
enabled=E2=80=9D is true?
And Does my DSP act by =E2=80=9COption 1=E2=80=9D or =E2=80=9COption2=E2=80=
=9D?
2- In spru288 (bootloader): when I use 16-bit parallel boot in data=20
space, to boot my information from RAM to DSP, which of =E2=80=9CPS & MSTRB=
=E2=80=9D=20
pins or =E2=80=9CDS & MSTRB=E2=80=9D pins is used?

Thanks

"oscillator enabled".  The data sheet means "internal oscillator".  A
crystal is not
an oscillator.

Not sure, but I would guess /DS strobe.
