SPI INTERRUPT AND STATUS FLAGS
The SPI interface has several status flags that indicate the status
of the double-buffered receive and transmit registers. Figure 96
shows when the status and interrupt flags are raised. The transmit
interrupt occurs when the transmit shift register is loaded with
not read before new data is ready to be loaded into the SPI/I 2 C
Receive Buffer SFR (SPI2CRx, 0x9B), an overflow condition has
occurred. This overflow condition, indicated by the SPIRxOF
flag, forces the new data to be discarded or overwritten if the
RxOFW bit is set.

If the SPI master is in transmit operating mode, and the SPI/I 2 C
Transmit Buffer SFR (SPI2CTx, 0x9A) register has not been
written with new data by the beginning of the next byte transfer,
