Delay from HEN Assertion to HREQ
Deassertion for RXL Read, TXL Write
See
This timing must be adhered to only if two consecutive writes to the TXL are executed without polling
TXDE or HREQ.
This timing must be adhered to only if two consecutive reads from one of these registers are executed
without polling the corresponding status bits or HREQ
HREQ is pulled up by a 1 k resistor.
Specifications are periodically sampled and not 100% tested.
May decrease to 0 ns for future versions.
