2) DRQ inactive to MASTER* inactive time
Description: The data sheet lists a minimum limit of 40ns for the time that DRQ goes inactive until MASTER* goes
inactive. During the course of device characterization a minimum value of less than 40ns has been observed.
The lower limit for this parameter therefore has been changed to 30ns. (DRQ inactive to MASTER* inactive time).
Implication: There is no jeopardy because of this change. The device tristates its active command, SBHE, SA, and
LA lines before MASTER* goes inactive.
Work-around: None required.
Status: Data sheet limit will be changed. There will be no change to the silicon.
3) DRQ inactive to Command, SBHE*, SA0-9 and LA17-23 tristated.
Description: The data sheet lists a maximum limit of 0ns for the time that DRQ goes inactive until Command,
SBHE*, SA0-9 and LA17-23 signals tristate. During the course of device characterization a maximum value of more
than 0ns has been observed. The upper limit for this parameter therefore has been changed to 10ns. (DRQ inactive
to Command, SBHE*, SA0-9 and LA17-23 tristated)
Implication: There is no jeopardy because of this change. The MASTER* which controls the IO on the bus goes
inactive after this time.
Work-around: None required.
Status: Data sheet limit will be changed. There will be no change to the silicon.
