If the requests are configured in DMA, read_count is assigned with ‘N’ when the DMA handler has completed its ‘N‘ CBASS0 accesses.
| Step | Register/Bit Field/Programming Model | Value |
|---|---|---|
| Start the channel | MCSPI_CHCTRL_0/1/2/3[0] EN | 1 |
| Wait until read_count = N | ||
| Stop the channel | MCSPI_CHCTRL_0/1/2/3[0] EN | 0 |
| Step | Register/Bit Field/Programming Model | Value |
