ATM Interconnect
19 Timing Requirements
19.1 Microprocessor Interface Timing
For access time information, see Section 6.3.2, CelXpres T8207 Access Performance.
1. write_access_active is the logical OR function of sel* and wr*_ds*.
2. Load is 15 pF.
Note: sel* and wr*_ds* must not have coinciding edges in opposite directions to prevent glitches on the write_access_active signal.
1. read_access_active is the logical OR function of sel* and rd*_wr*.
2. Load is 15 pF.
Note: sel* and rd*_wr* must not have coinciding edges in opposite directions to prevent glitches on the read_access_active signals.
