SCC - Serial Communication Controller
(Z85230) Tests
These sections describe the individual Serial Communication Controller
(SCC) tests. These tests are not available on the MVME230x boards.
Entering SCC without parameters causes all SCC tests to run in the order
shown in the table below, except as noted.
To run an individual test, add that test name to the SCC command.
The individual tests are described in alphabetical order on the following
pages.
Note These tests number the ports of the Z85230 starting with the first
Z85230 channel 0 as being port A, the second channel 1 as being
port B. For the PowerPC family of boards there are only ports A
and B.
You can use the CF command to select the ports to be tested. The
following example uses the CF command to select port 1, skipping port 0.
