20 Synchronous Serial Interface (SSC)
This chapter describes the two Synchronous Serial Interfaces, SSC0 and SSC1, of the
TC1796. It contains the following sections:
• Functional description of the SSC kernel, valid for SSC0 and SSC1
(see Page 20-1).
• SSC kernel register description, describes all SSC Kernel specific registers
(see Page 20-27).
• TC1796 implementation-specific details and registers of the SSC0/SSC1 modules
(port connections and control, interrupt control, address decoding, clock control, see
Page 20-46).
Note: The SSC kernel register names described in Section 20.2 will be referenced in
the TC1796 User’s Manual by the module name prefix “SSC0_” for the SSC0
interface and by “SSC1_” for the SSC1 interface.
