SCC - Serial Communication Controller (Z85230) Tests

http://www.motorola.com/computer/literature 3-119

Example:

PPC1-Diag>CF SCC

SCC Memory Space Base Address =80000840?RETURN

Internal-Loopback/Baud-Rates Port Mask =00000003? 2

(Bit 0 selects port 0, Bit 1 selects port 1; see note below.)

External-Loopback/Modem-Control Port Mask=00000003?

The first parameter is the base address space for the Z85230 devices. This

is preset for the PowerPC family of boards and should not be changed.

The next two parameters are the port selection masks. These masks are

used during testing to identify which ports are to be tested. The default is

to test every port. The Internal-Loopback/Baud-Rates Port Mask is used

for the BAUDS and ILPBCK test suites. The External-Loopback/Modem-

Control Port Mask is only used for the ELPBCK and MDMC test suites.
