† Characteristics are for clocked operation over the ranges of recommended operating temperature and supply voltage
‡ Typical figures are at 25°Cand are for design aid only: not guaranteed and not subject to production testing.
* This cycle time is for all accesses other than HDLC FIFOs. For HDLC FIFO accesses, a minimum 100ns is required between successive
