Sound Generator Operation with DMA
This section shows the flow of the Sound Generator operation with DMA.
DMAC writes a register related to DMA in the Sound Generator. The timing of the first interrupt with DMA
is different from the flow by MCU. The DMAC writes functional registers in the Sound Generator, through
the DMA Transfer Intermediate Register (SGDMAR) which works as a window register.
Note:
−
Software needs to set the Interrupt enable bit (SGCR.INTE="1") in order to use the Interrupt
request (PIRQ) as a DMA transfer request.
