Note
表6-1, Pin Attributes, does not take into account the subsystem multiplexing signals. Subsystem multiplexing signals are described in 节
6.3, Signal Descriptions.
4. MUXMODE: Multiplexing mode number:
a. MUXMODE 0 is the primary muxmode. 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 BALL RESET REL. MUXMODE column.
b. MUXMODE 1 through 7 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. Bootstrap are Special Configuration Pins, latched on rising edge of PORn / RESETFULLn. These are not programable MUXMODE.
d. An empty box means Not Applicable.
5. TYPE: This column describes functionality of the pin when configured for the given mux mode. It does not represent all capabilities of the pin, and as
such, there may be other mux mode configurations where these pins operate as a push-pull driver:
• I = Input
• O = Output
• IO = Input or Output
• IOD = Open drain terminal - Input or Output
• IOZ = Input, Output or Three-state terminal
• OZ = Output or Three-state terminal
• 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 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.
7. BALL RESET REL. MUXMODE: This muxmode is automatically configured at the release of the rstoutn signal.
An empty box means Not Applicable.
8. I/O VOLTAGE VALUE: This column describes the IO voltage value (the corresponding power supply).
An empty box means Not Applicable.
9. POWER: The voltage supply that powers the terminal IO buffers.
An empty box means Not Applicable.
