The following status bits are written by the SPI after it has finished transmitting the associ-
ated data buffer.
UN—Underrun
ME—Multi-Master Error
MOTOROLA
This bit is valid only when the SPI is configured as a master; it should be written as a zero
in slave mode.
The SPI encountered a transmitter underrun condition while transmitting the associated
data buffer. This error condition is valid only when the SPI is configured as a slave.
This buffer was closed because the SPISEL pin was asserted when the SPI was operating
as a master. This indicates a synchronization problem between multiple masters on the
SPI bus.
0 = The data buffer associated with this BD is not ready for transmission. The user is
1 = The data buffer, which has been prepared for transmission by the user, has not
0 = This is not the last BD in the Tx BD table.
1 = This is the last BD in the Tx BD table. After this buffer has been used, the CP will
0 = No interrupt is generated after this buffer has been serviced.
1 = The TXB or TXE bit in the event register is set when this buffer is serviced. TXB
0 = This buffer does not contain the last character of the message.
1 = This buffer contains the last character of the message.
0 = Normal operation.
1 = The R-bit is not cleared by the CP after this BD is closed, allowing the associated
