No
For crystal oscilla-
tor configurations
operating below
500kHz, the device
may generate a spu-
rious internal
Q-clock when
PORTA<0> switches
state.
TTL
It is recommended
that the
EEADR<7:6> bits
be cleared. When
either of these bits is
set, the maximum
I
higher than when
both are cleared.
PWRTE
R
If an interrupt occurs
while the Global
Interrupt Enable
(GIE) bit is being
cleared, the GIE bit
may unintentionally
be re-enabled by the
user’s Interrupt Ser-
vice Routine (the
RETFIE instruction).
