3. Module: Timer1
Typ
Section 11.1 (Timer1 Operation) is amended with
the following clarification:
When Timer1 is configured to operate as an asyn-
chronous counter, care must be taken that there is
no incoming pulse while the module is being
turned off. If an incoming pulse arrives while
Timer1 is being turned off, the value of register
TMR1 may become unpredictable.
If an application requires that Timer1 be turned off
and if it is possible that Timer1 may receive an
incoming pulse while being turned off, synchronize
the external clock first, by clearing the T1SYNC bit
of register T1CON. Please note that this may
cause Timer1 to miss up to one count.
