Note 1: In receive-only mode, the SPI transmission is triggered by reading the value of the SDRI
register. If SPI is not aborted in time, there may be a redundant transmission after the last reading
of the SDRI.
If you want to avoid the last redundant transmission, you can turn off SPIE after reading out the
data for the second time to the penultimate and wait for one SCK cycle. The transfer of SPI will be
aborted after the last data transfer is completed.
