Programmable clock out
A 50% duty cycle clock can be programmed to come out on P1.0. This pin, besides begin a regular
I/O pin, has two alternate functions. It can be programmed (1) to input the external clock for
Timer/Counter 2 or (2) to output a 50% duty cycle clock. An example is that the clock output ranges
from 61Hz to 4MHz at a 16MHz oscillator frequency if in 12T mode.
To configure the Timer/Counter 2 as a clock generator, bit C/ 2
T (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 this equation:
