bd082fa1f6 Do not initialize all pins to INPUT (#98) 
Comment out the initialization of all SAMD21 pins to INPUT to allow them to remain tri-stated by default.

98e2a3e429 Some fixes to the startup code - clocks configs (#89) 
* Reverted 1MHz clock generator to GCLK5 instead GCLK7
Fixed the clock divider of 1MHz clock generator to be 48 (its source is DFLL which clocking at 48MHz, so 48 / 48 = 1, it was 48 / 24 = 2).
Updated the PLLs to the proper Ratio afetr the change of the 1MHz clock source.
Disabled GCLK_GENCTRL_DIVSEL reg on the 12MHz clock generator, since this caused the clock to be 1.5MHz.

* Fixed a description comment.

d2620a72d2 Fix analog ref enums. (#83) 
AR_INTERNAL was removed in #74. Because of this, non-SAMD51 boards fail because AR_INTERNAL isn't defined.
This also define AR_INTERNAL_2V23, which is also used for non-SAMD51
boards.

2ca67fc36b Fix delayMicroseconds() on SAMD51 (#77) 
* Fix pulseIn() on SAMD51 by writing it in plain C, so that
the CM0+-specific pulse_asm won't need to be linked.
The SAMD51 is fast enough that we can time pulses with micros()
Tested with a bunch of pulse lengths from <1us to >1s

* Implement a new delayMicroseconds() function for SAMD51
This version enables the "Debug Watchpoint and Trace" module (DWT)
in startup.c and then uses the 32bit cycle counter that is part
of DWT to count cycles indepenent of instruction timing.
Tested for good accuracy with various values between 1 and 2000us.
