G.12 READI Electrical Characteristics
The AC electrical characteristics (56 MHz) are described in the following tables and figures
Figure G-29. Auxiliary Port Data Input Timing Diagram
Figure G-30. Auxiliary Port Data Output Timing Diagram
MDO and MSEO data is held valid until the next MCKO low transition.
When RSTI is asserted, EVTI is used to enable or disable the auxiliary port. Because MCKO probably is
not active at this point, the timing must be based on the system clock. Since the system clock is not realized
on the connector, its value must be known by the tool.
