(1) BALL NUMBER: Ball numbers on the bottom side associated with each signal on the bottom.
(2) BALL NAME: Mechanical name from package device (name is taken from muxmode 0).
(3) SIGNAL NAME: Names of signals multiplexed on each ball (also notice that the name of the ball is the signal name in muxmode 0).
(4) PINCNTL_REGISTER: APPSS Register name for PinMux Control
(5) PINCNTL ADDRESS: APPSS Address for PinMux Control
(6) MODE: Multiplexing mode number: value written to PinMux Cntl register to select specific Signal name for this Ball number. Mode column has bit range value.
(7) TYPE: Signal type and direction:
  • I = Input
  • O = Output
  • IO = Input or Output
(8) PULL UP/DOWN TYPE: indicates the presence of an internal pullup or pulldown resistor. Pullup and pulldown resistors can be enabled or disabled via software.
  • Pull Up: Internal pullup
  • Pull Down: Internal pulldown
  • An empty box means No pull.
(9) BALL STATE DURING RST: State of Ball during reset in the format of RX/TX/Pull Status
  • RX (Input buffer)
    • Off: The input buffer is disabled.
    • On: The input buffer is enabled.
  • TX (Output buffer)
    • Off: The output buffer is disabled.
    • Low: The output buffer is enabled and drives VOL.
  • Pull Status (Internal pull resistors)
    • Off: Internal pull resistors are turned off.
    • Up: Internal pull-up resistor is turned on.
    • Down: Internal pull-down resistor is turned on.
    • NA: No internal pull resistor.
  • An empty box, or "-" means Not Applicable.
(10) BALL STATE AFTER RST: State of Ball after reset in the format of RX/TX/Pull Status
  • RX (Input buffer)
    • Off: The input buffer is disabled.
    • On: The input buffer is enabled.
  • TX (Output buffer)
    • Off: The output buffer is disabled.
    • SS: The subsystem selected with MUXMODE determines the output buffer state.
  • Pull status (Internal pull resistors)
    • Off: Internal pull resistors are turned off.
    • Up: Internal pull-up resistor is turned on.
    • Down: Internal pull-down resistor is turned on.
    • NA: No internal pull resistor.
  • An empty box, NA, or "-" means Not Applicable.
(11) Pin Mux Control Value maps to lower 4 bits of register.
(12) Restricted use. Not available during deepsleep
