Input Pulse Rise and Fall Tim
1) Voltage referenced to ground.
4) Battery switchover occurs at the lower of either the battery voltage or VPF.
5) The IRQ /FT and RST outputs are open drain.
6) Using the recommended crystal on X1 and X2.
7) VCCO, CER , and OER pins open.
8) tAH1, tDH1 are measured from WE going high.
9) tAH2, tDH2 are measured from CE going high.
10) Typical measured with VBAT at 3.0V. Typical with ICCO = 100μA and VBAT = 3.0V is VBAT - 0.322.
