above. All request signals are deasserted if the SSP is disabled or the DMA enable signal is cleared.
The DMA operation of the SSP is controlled through SSPxDMACR register.

d. Overrun interrupt
interrupt is generated immediately after transfer. The data received after the overrun interrupt is gen-
erated (including the 9th data item) will become invalid and be discarded. However, if data is read
from the receive FIFO while the 9th data item is being received (before the interrupt is generated),
the 9th received data will be written in the receive FIFO as valid data. To perform transfer proper-
ly when the overrun interrupt has been generated, write "1" to SSPICR<RORIC> register, and then
read all data from the receive FIFO. Even if all the data is not read, data can be transmitted / re-
ceived if the receive FIFO has free space and the number of data to be transmitted does not exceed
the free space of the receive FIFO. Note that if the receive FIFO is not read (provided that the re-
ceive FIFO is not empty) within a certain 32-bit period (bit rate) after the overrun interrupt is
cleared, a time-out interrupt will be generated.
When the next data (9th data item) is received when the receive FIFO is already full, an overrun
