Pin Multiplexing

Table 4-28 describes the device pin multiplexing (no characteristics are provided in this table).

NOTE

Table 4-28, Pin Multiplexing doesn't take into account subsystem multiplexing signals. Subsystem multiplexing signals are described in

Section 4.3, Signal Descriptions.

NOTE

For more information, see the Control Module / Control Module Functional Description / Pad Configuration Registers section of the Device

TRM.

NOTE

Configuring two pins to the same input signal is not supported as it can yield unexpected results. This can be easily prevented with the

proper software configuration (Hi-Z mode is not an input signal).

NOTE

When a pad is set into a pin multiplexing mode which is not defined by pin multiplexing, that pad’s behavior is undefined. This should be

avoided.

NOTE

In some cases Table 4-28 may present more than one signal per muxmode for the same ball. First signal in the list is the dominant

function as selected via CTRL_CORE_PAD_* register.

All other signals are virtual functions that present alternate multiplexing options. This virtual functions are controlled via

CTRL_CORE_ALT_SELECT_MUX or CTRL_CORE_VIP_MUX_SELECT register. For more information on how to use this options,

please refer to Device TRM, Chapter Control Module, Section Pad Configuration Registers.

CAUTION

The IO timings provided in Section 5.9, Timing Requirements and Switching Characteristics are only valid if signals

within a single IOSET are used. The IOSETs are defined in the corresponding tables.
