Figure 12.3 shows an example for outputting an arbitrary duty pulse.
1. Clear the CCLR1 bit in TCR to 0 so that TCNT is cleared according to the compare match of
2. Set the OS3 to OS0 bits in TCSR to B'0110 so that 1 is output according to the compare match
According to the above settings, the waveforms with the TCORA cycle and TCORB pulse width
can be output without the intervention of software.

Description
The initial values should not be modified.
Input Select
Selects an internal synchronization signal (IVG signal) or
timer clock/reset input pin VSYNCI/TMIY (TMCIY/TMRIY)
as the signal source of external clock/reset input for the
TMR_Y counter.
0: IVG signal is selected
1: VSYNCI/TMIY (TMCIY/TMRIY) is selected
Counter clear
