Interface clock frequency. This is relative to the processor clock and in many cases is

100MHz. The number is represented as unsigned 16.16 format. Assuming a 100MHz processor
|
|
|
|
clock the minimum is 1.523kHz and maximum is 6.554THz. The actual interface clock
|
|
|
|
is CLK_FREQ * CLK_RATIO (see below). Note that the actual sampling clock may not be
|
|
|
|
the same as the interface clock- software must consider device specific implementation
|
|
|
|
parameters to calculate the final sampling clock.

Interface clock frequency. This is relative to the processor clock and in many cases is

|
|
|
100MHz. The number is represented as unsigned 16.16 format. Assuming a 100MHz processor
|
|
|
|
clock the minimum is 1.523kHz and maximum is 6.554THz. The actual interface clock
|
|
|
|
is CLK_FREQ * CLK_RATIO (see below). Note that the actual sampling clock may not be
|
|
|
|
the same as the interface clock- software must consider device specific implementation
|
|
|
|
parameters to calculate the final sampling clock.
