6.3.
The IDA0 output is connected to P1.6, and the IDA1 output is connected to P1.7. When the enable bit for
an IDAC (IDAnEN) is set to ‘0’, the IDAC output behaves as a normal GPIO pin. When the enable bit is set
to ‘1’, the digital output drivers and weak pull-up for the IDAC pin are automatically disabled, and the pin is
connected to the IDAC output. When using the IDACs, the IDAC pins should be skipped in the Crossbar by
setting the corresponding PnSKIP bits to a ‘1’. Figure 6.3 shows the pin connections for IDA0 and IDA1.
