NOTES:

1) ICC1T and ICC2T are specified with CE set to a logic 0 and EOSC bit = 0 (oscillator enabled).

2) ICC1A and ICC2A are specified with CE = VCC, SCLK=2MHz at VCC = 5V; SCLK = 500kHz

at VCC = 2.0V, VIL = 0V, VIH = VCC, and EOSC bit = 0 (oscillator enabled).

3) Measured at VIH = 2.0V or VIL = 0.8V and 10ms maximum rise and fall time.

4) Measured with 50pF load.

5) Measured at VOH = 2.4V or VOL = 0.4V.

6) ICC1S and ICC2S are specified with CE set to a logic 0. The EOSC bit must be set to logic 1

(oscillator disabled).

7) VCC = VCC1, when VCC1 > VCC2 + 0.2V (typical); VCC = VCC2, when VCC2 > VCC1.

8) VCC2 = 0V.

9) VCC1 = 0V.

10) VCC1 < VBAT.

11) VCCIF must be less than or equal to the largest of VCC1, VCC2, and VBAT.

12) Using a crystal on X1 and X2, rated for 6pF load.
