Part Number: TMS320F28P650SH
Tool/software:
the datasheet says,Crystal oscillator (X1 and X2) ground pin. When using an external crystal, do not connect this pin to the board ground. Instead, connect it to the ground reference of the external crystal oscillator circuit. If an external crystal is not used, this pin may be connected to the board ground.
Our question is, we use external crystal oscillator, the board ground on our board and the crystal oscillator are the same ground, if connected together, is it OK? Or does Vssosc need to be suspended?
