SCC - Serial Communication Controller (Z85230) Tests
In the first case, the Serial Port 3 Receiver (Z85230 Port A Rx, ISA DMA
Controller 1 and Channel 0) has reached terminal count before receiving
all the data. In the second case, the Serial Port 4 Receiver (Z85230 Port B
Rx, ISA DMA Controller 2 and Channel 5) has reached terminal count
before receiving all the data.
If the receiver buffer is filled with data before terminal count, it may still
be an incorrect match to the data transmitted. This results in an error:
SCC DMA: DMA Test...................Running ---> FAILED
SCC/DMA Test Failure Data:
(error message)
The Verify Counter used in this error message gives the amount of data
transferred correctly. The values in the two buffers that did not match are
shown also.
Refer to the section SCC Error Messages for a list of the error messages
and their meaning.
