When group m is playing, the output waveform is:
Note: For level with SAF1 active trigger mode, SAF1 is always enabled to issue the control output signal
in response to the playing trigger group.
If the output function is selected to be "FLASH", 4 flash styles can be selected by mask option. These flash
styles vary with control output pins as shown below:

Output flash pulses of 6 Hz, 50% duty cycle
Output flash pulses of 12 Hz, 50% duty cycle
If output types of SAF1 and SAF2 are both 'flash', they
can be chosen to flash with opposite phase (INV) or
synchronous (non-INV) to each other by mask option.
Output flash pulses flash with voice volumn
