- atusb.c (main), board.h (board_init), board.c (board_init): moved clock and I/O initialization to board file - board.h (led), board.c (led), atusb.c (main): abstracted LED setting in function "led" instead of open-coding it - spi.c (spi_init): set nSS to 1 before enabling the output, so that we don't generate what looks like an empty SPI transaction
