1-2% of devices experience reduced drive as
temperatures approach -40°C. This will result in a
loss of Timer1 counts or stopped Timer1
oscillation.
This can also prevent Timer1 oscillator start-up
under cold conditions.
Work around
Use of low-power crystals properly matched to the
device will reduce the likelyhood of failure. A 1mΩ
resister between OSC2 and V
improve the drive strength of the circuit.

A spurious Reset may occur if the Timer0/
Watchdog Timer (WDT) prescaler is assigned
from the WDT to Timer0 and then back to the
WDT.
Summary
The issue only arises when all of the below
conditions are met:
• Timer0 external clock input (TOCKI) is enabled.
• The Prescaler is assigned to the WDT, then to
• During the assignments, the T0CKI pin is high
• The 1:1 Prescaler option is chosen.

Description
On a POR, the Timer0/WDT prescaler is assigned
to the WDT.
If the prescaler is reassigned to Timer0 and
Timer0 external clock input (TOCKI) is enabled
then the prescaler would be clocked by a transition
on the TOCKI pin.
On power-up, the TOCKI pin is (by default)
enabled for Timer0 in the OPTION register.
If the T0CKI pin is:
• High and Timer0 is configured to transition on a
• Low and Timer0 is configured to transition on a
Then, if the prescaler is reassigned to the WDT, a
clock pulse to the prescaler will be generated on
the reassignment.
If the prescaler is configured for the 1:1 option, the
clock pulse will incorrectly cause a WDT Time-out
Reset of the device.

Disable the Timer0 external clock input by
clearing the TOCKI bit in the OPTION
register.
Modify the TOSE bit in the OPTION register to
the opposite configuration for the logic level
on the T0CKI pin.
Select a prescaler rate other than 1:1 and
issue a CLRWDT instruction before switching
to the final prescaler rate.
