MOTOROLA
This bit indicates that the RXFIFO has overflowed. At least one new written data word is lost. The RO
flag is automatically cleared after a data read.
This bit is set when the CSPI is in Slave CSPI FIFO advanced by SS_B rising edge mode and the slave
is receiving more than 16 bits in one burst. This bit is cleared after a data read from the SPIRXD register.
Because there are no error bits associated with individual RXFIFO data words this means that the entire
RXFIFO contents are suspect.
1 = RXFIFO has overflowed
0 = RXFIFO has not overflowed
1 = At least one data word in the RXFIFO had a bit count overflow error
0 = No bit count overflow
