Status Register Flags Behavior
Figure 27-7
Transmission Register Empty (TXEMPTY) status flags behavior within the SPI_SR (Status Reg-
ister) during an 8-bit data transfer in fixed mode and no Peripheral Data Controller involved.
Figure 27-8
of TX buffer (ENDTX), RX Buffer Full (RXBUFF) and TX Buffer Empty (TXBUFE) status flags
behavior within the SPI_SR (Status Register) during an 8-bit data transfer in fixed mode with the
Peripheral Data Controller involved. The PDC is programmed to transfer and receive three data.
The next pointer and counter are not used. The RDRF and TDRE are not shown because these
flags are managed by the PDC when using the PDC.
