Note 1 I_CC1 I_CC2 I_CC3 and I_CC4 are measured with no external drive (I_OH and I_OL e 0 I_IH and I_IL e 0) I_CC1 is measured with RESET e GND I_CC3 is measured
with NMI e V_CC I_CC4 is measured with NMI e GND CKI driven to V_IH1 and V_IL1 with rise and fall times less than 10 ns
Note 2 Test duration is 100 ms
Note 3 This is guaranteed by design and not tested
