When Timer1 is configured as timer running from the
main oscillator, PORTB<2:1> operate as normal I/O
lines. When Timer1 is configured to function as a
counter however, the clock source selection may affect
the operation of PORTB<2:1>. Multiplexing details of
the Timer1 clock selection on PORTB are shown in Fig-
ure 3-4 and Figure 3-5.
The clock source for Timer1 in the counter mode can
be from one of the following:

Table 5-1 shows the details of Timer1 mode selections,
control bit settings, TMR1 and PORTB operations.
