NOTE
For more information, see the Control Module / Control Module Functional Description / PAD Functional Multiplexing and Configuration
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 multiplexing mode which is not defined by pin multiplexing, that pad’s behavior is undefined. This should be
avoided.
NOTE
In some cases Table 4-3 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.
NOTE
ECC is not available on this device, but signal names are retained for consistency with the DRA7xx family of devices.
CAUTION
The I/O timings provided in Section 7, Timing Requirements and Switching Characteristics are valid only if signals within
a single IOSET are used. The IOSETs are defined in the corresponding tables.
NOTE
Dual rank support is not available on this device, but signal names are retained for consistency with the DRA7xx family of devices.
