Formula 6: T
QUI
, T
RDY
and min T
SDR
For access monitoring (T
WD
) and Target Rotation Time (T
TR
):
T
WD
> T
TR
Formula 7: T
WD
and T
TR
For the Data_Control_Time the following rule applies:
Data_Control_Time > 6 * T
WD
Formula 8: Data_Control_Time
If the devices used have different values for min T
SDR
then the
greatest of these values is used for all devices.
Min T
SDR
= max (min T
SDR device 1
, min T
SDR device 2
, ..., min T
SDR device
N
)
Formula 9: Min T
SDR
Example: If for device 1 the value for min T
SDR
200, for device 2 the values 75 and for device 3 the value 125,
then the value of 200 must be used for all devices.
The same applies also for the Bus parameters max T
SDR
, T
