Data-In Burst Host Termination Timing), and tLI indicate sender-to-recipient or 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.

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.

Notes: 1) All timing measurement switching points(low to high and high to low) shall be taken at 1.5 V.

2) The correct data value shall be captured by the recipient given input data with a slew rate of 0.4

V/ns rising and falling and the input STROBE with a slew rate of 0.4 V/ns rising and falling at tDSIC

and tDHIC timing (as measured through 1.5 V).

3) The parameters tDVSIC and tDVHIC shall be met for lumped capacitive loads of 15 and 40 pF at

the IC where all signals have the same capacitive load value. Noise that may couple onto the output

signals from external sources has not been included in these values.
