Assigned PIO Lines, Disconnection Possibility
Table 4-5. Audio Input Configuration
Some test points have been placed on the SAM4S-EK2 board for the verification of important signals.
Table 4-6. Test Points
As pointed out in some previous interface description, 0 Ohm resistors have been inserted on the path of
the receiver PIO lines of the SAM4S-EK2. These are the PIO lines connected to an external driver on the
board. The 0 Ohm resistors allow disconnecting each of these for custom usage (through PIO expansion
connectors for example). This feature gives the user an added level of versatility for prototyping a system
of his own. See the table below.
