1

Pull-ups are not active when GPIO functions are selected for the pins.

2

The primary functionality of a pin is not necessarily its default functionality. Pins that have GPIO functionality will 
default to GPIO inputs.

3

Pull-up is active only with the SYNCA function.

4

Pull-up is active only with the SYNCB function.

5

Pull-up is active only with the SDA function.

6

Pull-up is active only with SCL function.

7

Pull-up is active when JTAG_EN is driven high.
