Interfaces of the SSC Modules
In the XC164 the SSC modules are connected to IO ports and other internal modules
according to Figure 20-8 and Figure 20-9.
The input/output lines of SSC0 are connected to pins of Ports P3, while the input/output
lines of SSC1 are connected to pins of Ports P1H. The three interrupt request lines of
each module are connected to the Interrupt Control Block.
Clock control and emulation control of the SSC Module is handled by the System Control
Unit, SCU.
