7.2 Signal Descriptions

Note:

All digital IO pins of the device (except NERROR IN, NERROR_OUT, and WARM_RESET) are non-failsafe; hence, care needs to be taken that they are not driven externally without the VIO supply being present to the device.

Note:

The GPIO state during the power supply ramp is not ensured. In case the GPIO is used in the application where the state of the GPIO is critical, even when NRESET is low, a tri-state buffer should be used to isolate the GPIO output from the radar device and a pull resister used to define the required state in the application. The NRESET signal to the radar device could be used to control the output enable (OE) of the tri-state buffer.

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:
