Real Time Output Control (Port 1)

P10 , P12 and P14 has a real time output function that can switch pin's output at the falling edge of the
external interrupt 0 pin (P20/IRQ0).
Real time control can change timer output signal (PWM output, timer pulse output, remote control carrier
output), without setting on the program, in synchronization with external event. Output levels to be
switched at event generation are 3 ; "0", "1" and "high impedance (Hi-z)".
