Default Routing Function (After RESET)
The default routing paths are shown in Figure 32. MPIO_A0-A3 are selected by CLKST, VOUT, XMCKO, and
INT0. Note that by default, MPIO_A0-A3 pins are Hi-Z as set by Registers MPA0HZ, MPA1HZ, MPA2HZ, and
MPA3HZ.
Figure 32. Default Routing Block Diagram
By default, the ADC starts up as a clock slave to the crystal that is connected to the PCM9211. The DIR receives
data on RXIN2. When the DIR is unlocked, the ADC has priority, and uses the Main port. When the DIR is
locked, data from the MAIN PORT are DIR data.
