The read transfer operation completes after 224 system DMA RX requests. The receive FIFO never overflows. If the FIFO becomes full, the MMC.CLK signal is momentarily stopped until the system DMA or the local host performs a read access, which starts emptying the FIFO. Figure 19 shows a ...
• Independent control of transmit, receive, line status, data set interrupts, and FIFOs. • SIR-IrDA encoder/decoder (from 2400 to 115 kBd). • Supports maskable interrupts. • Supports DMA transfers. 6.25 Pulse Code Modulation (PCM) interface The PCM interface supports the PCM and ...
If this option is not given then these functions will silently discard their buffer size argument - this means you are not getting any overflow checking in this case. - Boot Delay: CONFIG_BOOTDELAY - in seconds Delay before automatically booting the default image; set to -1 to disable ...

This additional information specified in the controller ensures that the controller sends a read command only if there is space equal to the card read threshold available in the RX FIFO buffer. This in turn ensures that the card clock is not stopped in the middle a block of data being ...
