When the PRNT bit of TSCR1 register is set to 1, all bits are used to set a more precise delay.
the delay settings in this case. After detection of a valid edge on an input capture pin, the delay counter counts
the pre-selected number of [(dly_cnt + 1)*4]bus clock cycles, then it will generate a pulse on its output if the level
of input signal, after the preset delay, is the opposite of the level before the transition.This will avoid reaction to
narrow input pulses.
Delay between two active edges of the input signal period should be longer than the selected counter delay.
Note: It is recommended to not write to this register while the timer is enabled, that is when TEN is set in register
