•
PWM Period
: Set the low-speed PWM Period for one bit.
Min: 111.11ns
Default: 222.22ns
Max: 333.33ns
•
PWM Ratio
: This sets the ratio of the duration of the longer of the two
sub-phases in a PWM bit to the PWM bit duration.
•
Min. Variation
: M-PHY allows a variation of the bit duration in PWM
mode. Min. Variation defines the deviation that gives the shortest
generated bit duration.
•
Max. Variation
: The deviation that gives the longest generated bit
duration.
•
Variation Speed
: The bit variability is a sinusoidal function that varies
between the minimum PWM period and the maximum PWM period.
The period of this function is defined as variation speed.
A positive number defines how fast the PWM bit duration should
change compared to the previous PWM bit. The greater the number,
the slower the rate of change.
Example
: If the value is 10, then the sinusoidal function has a period of
10 PWM bits.
If the variation speed value is negative, then the speed value gives the
number of cycles per burst.
Example:
For a burst with 250 PWM bits and a '-10' (negative) speed,
the variation period is 25 PWM bits.
•
PWM Bit Resolution
: This read-only value gives the number of bits per
PWM period.
