Comparator: To change the output status while a match occurs. The TMR1IF flag
will be set at the same time.
TMR17~TMR10 is bit set of Timer1 register and it increases until the value
matches the PWP and then it resets to 0.
PWP7~PWP0 is bit set of pulse width preset for the desire width of baud clock
in advance.
