I have two questions on SCSI reset signal.

[1] If a SCSI device sees that the RST signal is
asserted for 300 ns (or any value greater than reset
delay period of 200 ns, should the device take it as a
valid reset and release the all the bus signals within
the bus clear delay  from transition to RST true?

[2] If the above is true (that is, a RST assertion of
more than reset delay is a valid reset), what is the
margin available for the SCSI device to detect a valid
RST vs rejecting it as a glitch (in terms of time)?

thanks for your time,
