Sampling rate
: Set/display a sampling rate(frequency).
You can set a sampling rate(frequency) by 1KHz each.
For SPI, a sampling rate(frequency) will be set at an
approximate value which can be really set.
(I2C:47KHz - 1MHz / SPI: Up to 12MHz)
* For how to calculate an approximate value,
please refer to a usb61_spi_set_freq() function at
Chapter 4.
