Utilizing the Atmel RapidS Function
To take advantage of the Atmel
must be used to transmit data back and forth across the serial bus. The Atmel DataFlash
clock its data out on the falling edge of the SCK signal and clock data in on the rising edge of SCK.
For full clock cycle operation to be achieved, when the DataFlash is clocking data out on the falling edge of SCK,
the host controller should wait until the next falling edge of SCK to latch the data in. Similarly, the host controller
should clock its data out on the rising edge of SCK in order to give the DataFlash a full clock cycle to latch the
incoming data in on the next rising edge of SCK.
