/**
|
|
* CoolRunner (HackRF) CPLD:
|
|
* CoolRunner-II devices have internal pull-ups on TDI, TMS, and TCK.
|
|
* It is not necessary to externally terminate JTAG pins with internal termination; they can be
|
|
* left floating. External pull-ups on pins with internal termination is allowed, but not
|
|
* necessary. External pull-down termination is not recommended as it would conflict with
|
|
* the internal pull-ups
|
|
*
|
|
* LPC43xx pull-ups come on line when 3V3 supply voltage reaches about 2V.
|
|
*
|
|
* 3V3 supply:
|
|
* Ramps up in about 1ms.
|
|
*
|
|
* 1V8 supply:
|
|
* Ramps up in about 1ms.
|
|
* EN1V8 has a 10K pull-down on the HackRF and is pulled up (very gently) by the LPC43xx
|
|
* bootloader at boot time. So until the EN1V8 pin is reconfigured as an output, the enable
|
|
* pin on the 1V8 supply sits at about 0.55V, which feels untidy...
|
|
* 1V8 supply is activated when GPIO is driven high by user code.
