/* TDI and TMS pull-ups are required in all JTAG-compliant devices.
*
* The HackRF CPLD is always present, so let the CPLD pull up its TDI and TMS.
*
* The PortaPack may not be present, so pull up the PortaPack TMS pin from the
* microcontroller.
*
* TCK is recommended to be held low, so use microcontroller pull-down.
*
* TDO is undriven except when in Shift-IR or Shift-DR phases.
* Use the microcontroller to pull down to keep from floating.
*
* LPC43xx pull-up and pull-down resistors are approximately 53K.
