A 50% duty cycle clock can be programmed to come out on
P1.0, as shown. This pin, besides being a regular
I/O pin, has two alternate functions. It can be
programmed to input the external clock for Timer/Counter 2
or to output a 50% duty cycle clock ranging from 61 Hz to 4
MHz at a 16 MHz operating frequency.
To configure the Timer/Counter 2 as a clock generator, bit
C/T2 (T2CON.1) must be cleared and bit T2OE (T2MOD.1)
must be set. Bit TR2 (T2CON.2) starts and stops the timer.
The clock-out frequency depends on the oscillator frequency
and the reload value of Timer 2 capture registers
(RCAP2H, RCAP2L), as shown in the following equation.

                       Oscillator Fequency 
Clock-Out Frequency =  ------------------------------
                       4 x [65536 - (RCAP2H, RCAP2L) ]


In the clock-out mode, Timer 2 roll-overs will not generate
an interrupt. This behavior is similar to when Timer 2 is
used as a baud-rate generator. It is possible to use Timer 2
as a baud-rate generator and a clock generator simultaneously.
Note, however, that the baud-rate and clock-out
frequencies cannot be determined independently from one
another since they both use RCAP2H and RCAP2L.
