13.2.4
When TMR3CS is set, the 16-bit TMR3 increments on
the falling edge of clock input TCLK3. The input on the
RB5/TCLK3 pin is sampled and synchronized by the
internal phase clocks, twice every instruction cycle.
This causes a delay from the time a falling edge
appears on TCLK3 to the time TMR3 is actually incre-
mented. For the external clock input timing require-
ments, see the Electrical Specification section.
Figure 13-7 shows the timing diagram when operating
from an external clock.

Since Timer3 is a 16-bit timer and only 8-bits at a time
can be read or written, care should be taken when
reading or writing while the timer is running. The best
method is to stop the timer, perform any read or write
operation and then restart Timer3 (using the TMR3ON
bit). However, if it is necessary to keep Timer3 free-
running, care must be taken. For writing to the 16-bit
TMR3, Example 13-2 may be used. For reading the 16-
bit TMR3, Example 13-3 may be used. Interrupts must
be disabled during this routine.
to timer increment is between 2Tosc and 6Tosc.
