When delay time is unnecessary, invert timer flip-flop TB0FF0 when the up counter
value is loaded into capture register (TB0CP0H/L), and set the TB0CP0H/L value (c)
plus the one –shot pulse width (p) to TB0RG1H/L when the interrupt INT6 occurs.
The TB0FF0 inversion should be enabled when the up counter (UC10) value matched
TB0RG1H/L, and disabled when generating the interrupt INTTB01.
