MICROCIRCUIT DATA SHEET
(Continued)
Note 5: ACTNd and ACTNs are tied together
Note 6: TX collision extension has already been performed and no other port is driving ANYXN.
Note 7: Includes TW2
Note 8: PKEN assumed high
Note 9: Assuming reception ended before COLN goes inactive. TW2 is included in this
parameter. Assuming ACTNd to ACTNs delay is 0.
Note 10: In a Multi-RIC system, the PKEN signal is valid only for the first receiving RIC.
Note 11: The preamble on this bus consists of the following string: 01011
Note 12: Minimum high time between read/write cycles is 100nS.
Note 13: Assuming zero propagation delay on external buffer.
Note 14: The data will always TRI-STATE before BUFEN goes active with a load of 100pF on the
data bus.
Note 15: When RDY is used, the minimum 600nS write width does not have to be maintained.
