NOTE
In some cases Table 4-2 may present more than one signal name 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.
4. MUXMODE: Multiplexing mode number:
(a) MUXMODE 0 is the primary mode; this means that when MUXMODE=0 is set, 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 mode 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.
5. 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
6. BALL RESET STATE: The state of the terminal at power-on reset:
– drive 0 (OFF): The buffer drives V_OL (pulldown or pullup resistor not activated)
– drive 1 (OFF): The buffer drives V_OH (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
7. 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 V_OL (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 V_OH (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
NOTE
For more information on the CORE_PWRON_RET_RST reset signal and its reset sources,

Description section of the Device TRM.
8. BALL RESET REL. MUXMODE: This muxmode is automatically configured at the release of the
