EEADR<7:6> and IDD
It is recommended that N/A
the EEADR<7:6> bits be
cleared. When either of
these bits is set, the maxi-
mum IDD for the device is
higher than when both are
cleared.

circuits
REXT = 5k - 100k
GIE bit unintentional
enable
If an interrupt occurs while N/A
the Global Interrupt
Enable (GIE) bit is being
cleared, the GIE bit may
unintentionally be re-
enabled by the user’s
Interrupt Service Routine
(the RETFIE instruction).
