2.2 Header and Jumper Information

The TMUXS7614DEVM has various headers that provide various points of functionality on the board. From left to right:

  1. J8, J9, J10 and J11 provide a means of accessing signal paths for S1-S8 and D1-D8.
  2. J20 allows users to place a jumper to choose whether hardware reset is performed by the reset button (position A) or by an outside source (position B). If position B is chosen, then the device resets when a rising pulse is applied to EXT_RESET.
  3. J13 provides an interface to tap into the SDL, SCLK and /CS pins.
  4. J17 allows you to place a jumper to choose whether VL is driven by the USB2ANY (VIO) or an external source (EXT_VL)
  5. J6 allows users to place a jumper to control whether the SPI_PICO_Out signal path propagates onto another EVM or device. No jumper on J6 allows for read back via the SDO feedback signal path.
  6. Place a jumper across J15, J16 and J18 to utilize the J14 power block.
  7. J12 provides a block to interface with the VDD_D, GND_D, /RESET/VL_D, SDO, SCLK_D and /CS_D pins.
