/* SPI interface:
** byte_count = transfer length
** mosi[] = array of master-out, slave-in data bytes
** miso_buf[] = receive buffer for master-in, slave-out data bytes
**
** 04/07/2004: master-in slave-out data from MAX1258 is delayed one clock cycle.
** When instructed to transfer n bytes, the hardware must generate
** n * 8 clock pulses. However, the first bit of miso_buf[] must be sampled
** concurrent with the SECOND bit of mosi[].
** The final bit of miso_buf[] does not get a clock pulse, instead the
** final state of the MAX1258 DOUT pin is sampled prior to negating CS.
