Terminal Configuration and Functions

NOTE

In some cases Table 4-1 may present more than one signal name per muxmode for the

same

ball.

First

signal

the

list

the

dominant

function

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.

4. PN: This column shows if the functionality is applicable for AM5746 device. Note that the Pin Attributes

table presents a functionality of super set. If the cell is empty it means that the signal is available in all

devices.

– Yes - Functionality is presented in AM5746

– No - Functionality not presented in AM5746

An empty box means Yes.

5. MUXMODE: Multiplexing mode number:

a. MUXMODE 0 is the primary muxmode; this means that when MUXMODE = 0, the function

mapped on the pin corresponds to the name of the pin. The primary muxmode is not necessarily

the default muxmode.

NOTE

The default muxmode is the mode at the release of the reset; also see the RESET REL.

MUXMODE column.

b. MUXMODE 1 through 15 are possible muxmodes for alternate functions. On each pin, some

muxmodes are effectively used for alternate functions, while some muxmodes are not used. Only

MUXMODE values which correspond to defined functions should be used.

c. An empty box means Not Applicable

6. TYPE: Signal type and direction:

–

I = Input

–

O = Output

–

IO = Input or Output

–

D = Open drain

–

DS = Differential Signaling

–

A = Analog

–

PWR = Power

–

GND = Ground

–

CAP = LDO Capacitor

7. BALL RESET STATE: The state of the terminal at power-on reset:

–

drive 0 (OFF): The buffer drives VOL (pulldown or pullup resistor not activated).

–

drive 1 (OFF): The buffer drives VOH (pulldown or pullup resistor not activated).

–

OFF: High-impedance

–

PD: High-impedance with an active pulldown resistor

–

PU: High-impedance with an active pullup resistor

–

An empty box means Not Applicable

8. BALL RESET REL.STATE: The state of the terminal at the deactivation of the rstoutn signal (also

mapped to the PRCM SYS_WARM_OUT_RST signal).

–

drive 0 (OFF): The buffer drives VOL (pulldown or pullup resistor not activated).

–

drive clk (OFF): The buffer drives a toggling clock (pulldown or pullup resistor not activated).

–

drive 1 (OFF): The buffer drives VOH (pulldown or pullup resistor not activated).

–

OFF: High-impedance

–

PD: High-impedance with an active pulldown resistor
