2) 80-conductor cabling shall be required in order to meet setup (tDS, tCS) and hold (tDH, tCH) times
in modes greater than 2.
3) Timing for tDVS, tDVH, tCVS and tCVH shall be met for lumped capacitive loads of 15 and 40 pF
at the connector where the Data and STROBE signals have the same capacitive load value. Due to
reflections on the cable, these timing measurements are not valid in a normally functioning system.
4)For all modes the parameter tZIORDY may be greater than tENV due to the fact that the host has
a pull-up on IORDY- giving it a known state when released.
5)The parameters tDS, and tDH for mode 5 are defined for a recipient at the end of the cable only in
a configuration with a single device located at the end of the cable. This could result in the minimum
values for tDS and tDH for mode 5 at the middle connector being 3.0 and 3.9 ns respectively.
2) The correct data value shall be captured by the recipient given input data with a slew rate of 0.4
2) The parameters tDVSIC and tDVHIC shall be met for lumped capacitive loads of 15 and 40 pF at

recipient-to-sender interlocks, i.e., one agent (either sender or recipient) is waiting for the other
agent to respond with a signal before proceeding. tUI is an unlimited interlock that has no
maximum time value. tMLI is a limited time-out that has a defined minimum. tLI is a limited
time-out that has a defined maximum.
