This read-only bit indicates that the I2C master function is present when it reads back a one. This I2C function
is not available on a device that returns a zero for this bit field.
0x0

This read-only bit indicates that the I2C slave function is present when it reads back a one. This I2C function
is not available on a device that returns a zero for this bit field.
0x0
0x1
This read-only bit indicates that the I2C controller has at least one enable interrupt requesting service. It is
the logic OR of all of the IRQ summary bits.
