The following list describes the table column headers:

  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 ADDRESS: MSS Address for PinMux Control
  5. 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.
  6. TYPE: Signal type and direction:
    • I = Input
    • O = Output
    • IO = Input or Output
  7. BALL RESET STATE: The state of the terminal at power-on reset
  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. Pin Mux Control Value maps to lower 4 bits of register.

IO MUX registers are available in the MSS memory map and the respective mapping to device pins is as follows:
