"spi_io"

it work in our context
- usb.sch: cleaned up programming/auxiliary/LED signals
- usb.sch: swapped LED and nRST_RF (tracking the layout)
- atusb.brd: updated for corrected netlist
- atusb.brd: moved date code which overlapped with traces
- atusb.brd: reduced front RF and power ground zones to avoid ground
fill between transceiver pads
- atusb.brd: added ground traces around crystal to widen ground zone
- atusb.pro, atusb.cmp: updated for ATmega32U2-based design
- usb.sch: rearranged LED, nRST_RF, and SLP_TR, to make layout easier
- atusb.brd: redid layout for the ATmega32U2-based design
- usb.sch: renumbered test points for serial programming
- usb.sch: moved everything down to make room on top
- usb.sch: moved description of pad placement near the pads
- usb.sch: added footprint of U1
- atusb.pro (LibName5): changed from c8051f326 to atmega8u2
- atrf.sch: export CLKM and added filter for 8 MHz clock
- atusb.sch: connect CLK between RF and USB side
- usb.sch: changed design frim C8051F326 to ATmega32U2 (needs cleanup)
Settings according to
http://www.nxp.com/documents/mounting_and_soldering/AN10365.pdf
