(1) The internal pullups on the CTL-I
2
C and SR-I
2
C balls are used for test purposes or when the SR-I
2
C interface is not used. Discrete
pullups to the VIO supply must be mounted on the board in order to use the I
2
C interfaces. The internal I
2
C pullups must not be used for
functional applications
