INTER-INTEGRATED CIRCUIT 1 (I2C1)
McBSP1 external clock source (as opposed to internal) (

(I/O/Z).
This pin
must
be externally pulled up. When this pin is used as an I2C pin, the
value of the pullup resistor is dependent on the number of devices connected to
the I2C bus. For more details, see the

IPD = Internal pulldown, IPU = Internal pullup. [These IPD/IPU signal pins feature a 13-k
resistor (approximate) for the IPD or 18-k
resistor
(approximate) for the IPU. An external pullup or pulldown resistor no greater than 4.4 k
and 2.0 k
, respectively, should be used to pull a signal
to the opposite supply rail.]
