* Number of least-significant bits which are stripped away during ramp evaluation.
|
|
* This setting allows to specify larger ramps at the price of less precision.
|
|
*
|
|
* The maximum ramp size allowed is 2^(24 + RAMP_CLOCK_SHIFT_PRECISION), in clocks.
|
|
* For instance, using RAMP_CLOCK_SHIFT_PRECISION 1, and a 8x prescaler, the maximum
|
|
* length of a ramp is about 6.7 secs. Raising RAMP_CLOCK_SHIFT_PRECISION to 2
|
|
* brings the maximum length to 13.4 secs, at the price of less precision.
|

*
|
|
* ramp_compute() will check that the length is below the maximum allowed through
|
|
* a runtime assertion.

*
|
|
* \note This macro is used only for the fixed-point version of the ramp.
