Sound Generation Logic (SGL)

In other cases, where SOUND_DURATION counter has no role to play, the sound generation stops when
the SOUND_CTRL[0:2] bits are changed asynchronously by the software.
34.4.1 Interrupts
SGL generates the interrupt signal ipi_int_sgl. The generation of this interrupt is enabled if the
MODE_SEL[SDCIE] bit is 1. If this bit is 0, then the interrupt is disabled.
The interrupt is generated whenever the SOUND_DURATION counter reaches 0 in cases where sound is
being generated for a predetermined duration of time (i.e., SOUND_DURATION register value is
controlling sound duration).
The SGL_STATUS[SDCIF] bit indicates the generation of interrupt. It is set whenever an interrupt is
generated irrespective of the value of the SDCIE bit. It can be cleared by writing 1 to it.
The interrupt signal ipi_int_sgl is asserted if the SDCIF flag is set and the SDCIE bit is set.
