Atmel AT45DB161D
MOSI = Master Out, Slave In
MISO = Master In, Slave Out
The Master is the host controller and the Slave is the Atmel DataFlash
The Master always clocks data out on the rising edge of SCK and always clocks data in on the falling edge of SCK.
The Slave always clocks data out on the falling edge of SCK and always clocks data in on the rising edge of SCK.

Master clocks out first bit of BYTE-MOSI on the rising edge of SCK
Slave clocks in first bit of BYTE-MOSI on the next rising edge of SCK
Master clocks out second bit of BYTE-MOSI on the same rising edge of SCK
Last bit of BYTE-MOSI is clocked out from the Master
Last bit of BYTE-MOSI is clocked into the slave
Slave clocks out first bit of BYTE-SO
Master clocks in last bit of BYTE-SO
