Description

Configure the VCCA_GXB voltage for a GXB I/O pin by specifying the intended VCCA_GXB voltage for

a GXB I/O pin. If you do not make this assignment the compiler automatically sets the correct

VCCA_GXB voltage depending on the configured data rate, as follows:
• Data rate <= 6.5 Gbps: 2_5V

• Data rate > 6.5 Gbps: 3_0V.

Options

• 2_5V

• 3_0V
