NOTES:
1) I
CC1T
and I
CC2T
are specified with CE set to a logic 0 and
EOSC
bit = 0 (oscillator enabled).
2) I
CC1A
and I
CC2A
are specified with CE = V
CC
, SCLK=2MHz at V
CC
= 5V; SCLK = 500kHz
at V
CC
= 2.0V, V
IL
= 0V, V
IH
= V
CC
, and
EOSC
bit = 0 (oscillator enabled).
3) Measured at V
IH
= 2.0V or V
IL
= 0.8V and 10ms maximum rise and fall time.
4) Measured with 50pF load.
5) Measured at V
OH
= 2.4V or V
OL
= 0.4V.
6) I
CC1S
and I
CC2S
are specified with CE set to a logic 0. The
EOSC
bit must be set to logic 1
(oscillator disabled).
7) V
CC
= V
CC1
, when V
CC1
> V
CC2
+ 0.2V (typical); V
