CardAccessSpeed

Select best possible memory access speed.

This function is used to set memory access speed for all CPU accesses to card memory.

Typically this information would be determined by first examining the Card Information Structure.

Then you would use this function to let the card.resource select the best possible access speed for you, however note that the range of possible access speeds may vary on some machines (depending on the type of credit-card interface hardware being provided).

handle

Same handle as that used when OwnCard() was called.

nanoseconds

Preferred access speed in nanoseconds.

Speed

Access speed selected by resource (in nanoseconds).

0

Not successful. Either because the credit-card was removed, or the access speed you requested is slower than that supported by the credit-card interface hardware.

This function may be called from within a task, or from a level 1 or level 2 interrupt.
